Rodent Repellent Brand Case Study: $30 Item to $177 Orders
A $29.95 rodent repellent kept $7.73 per sale on Amazon. On Shopify the same product kept $78.87 per sale, after ads and inventory, because the order grew to $177.75.
A $29.95 product can't afford a $63.40 ad bill.
That's the first thing I'd have told you. And I'd have been wrong.
This rodent repellent brand case study is the proof. A $29.95 rodent repellent kept $7.73 per sale on Amazon after fees, shipping, inventory and ads. The same product, moved to Shopify and repriced at $49.95, kept $78.87 per sale after paying for ads and inventory. The ad cost per order went up more than 10x. The profit per sale went up more than 10x anyway. The reason sits in one line of the breakdown: the average order went from $29.95 on Amazon to $177.75 on Shopify.
Real client numbers, not typical results, and not a promise of what your store will do.
The product was cheap. The order didn't have to be.
Here's every line, and what each one means for your own best seller.
What did a $29.95 rodent repellent keep per sale on Amazon?
The product is listed on /results as Smart Rodent. On Amazon it was doing $10K a month at a $30 price. That's a product that works. Reviews, rank, repeat buyers. From the outside, healthy.
Here's one sale, straight from the breakdown on our results page:
| Smart Rodent on Amazon FBA | Per sale |
|---|---|
| Product price | $29.95 |
| Landed cost | -$7.50 |
| Shipping fees | -$4.24 |
| Platform fees (15%) | -$4.49 |
| Gross profit per sale | $13.72 |
| Advertising | -$5.99 |
| Net profit per sale | $7.73 |
Run it on a napkin. $29.95 minus $7.50, minus $4.24, minus $4.49 leaves $13.72. Take out $5.99 in ads and you're holding $7.73. That's the contribution margin after ads, the line our guide to contribution margin for ecommerce tells you to watch above every other.
That 15% line is standard. Amazon's own seller pricing page lists a 15% referral fee, with a $0.30 minimum, for Lawn and Garden, Home and Kitchen, and Tools and Home Improvement, the categories where a repellent tends to live. It's charged on the sale price, every sale, before you've paid for the product or the box.
I sold on Amazon for years, so let me be plain about what $7.73 is. It's a skinny order. You carry the inventory, you eat the stockouts, you answer the reviews, and the marketplace hands you $7.73 for the trouble. $10K a month in sales sounds like a brand. At $7.73 a sale it's closer to a job with no boss and no benefits.
What did the same product keep on Shopify?
Here's the full breakdown, side by side, exactly as it appears on /results:
| Amazon FBA | Shopify + RevenueFlows AI | |
|---|---|---|
| Product price | $29.95 | $49.95 |
| Landed cost | -$7.50 | -$7.50 |
| Shipping fees | -$4.24 | -$6.30 |
| Platform fees | -$4.49 (15%) | -$1.50 (3%) |
| Gross profit | $13.72 | $34.65 |
| Advertising | -$5.99 | -$63.40 |
| Average order value | $29.95 | $177.75 |
| Net profit per sale | $7.73 | $78.87 |
Read the Shopify column carefully, because this is where most people misread a case study like this. The price, landed cost, shipping and fee lines are per unit of the $49.95 product. The advertising and net profit lines are per order. And the order averaged $177.75. That's how a $63.40 ad line can sit on top of a $34.65 gross profit per unit and still leave $78.87 in the bank.
Three things changed between the columns.
The price went up $20, from $29.95 to $49.95. Off the marketplace, the product stops sitting in a search result beside six cheaper lookalikes.
The platform cut fell from 15% to 3%, which on a $49.95 unit is $1.50 instead of $4.49. Shopify's pricing page shows online card rates in the low single digits per order on its standard plans, a long way from a 15% referral fee.
And the order got fat. $29.95 on Amazon. $177.75 on Shopify. Almost 6x more money through the checkout, and a little over three and a half times the new sticker price in every cart.
Real client numbers from the breakdown on /results. Not typical results, not a promise.
Monthly revenue followed. $10K a month on Amazon became $23K a month on Shopify, and the proof screenshots on /results show monthly sales between $15K and $20K and a $178 average order value.
How does a $30 item become a $177 order?
Here's the thing. The breakdown tells you what happened to the order. It doesn't tell you how. So I'll tell you the mechanics we use on pages like this. These are the levers, not a line item from the table, so treat them as the method and not as extra measured results.
Nobody with a rodent problem has one rodent. They have a garage, an attic, a shed, a crawlspace, and a kitchen cupboard they'd rather not talk about. On Amazon the listing sells one unit, because that's what a listing is built to do: one product, one price, one buy box. The buyer solves one room and comes back in six weeks for the next one, if they remember you.
On Shopify the page gets to ask a better question: how many places do you need covered? That one question changes the shape of the order.
So the page we build leads with the outcome, a home that stays clear, instead of a unit. The default offer is the multi-pack, with the single unit available but not the hero. The quantity tiers are priced so the third and fourth unit feel like the obvious move. And the add-ons that make sense beside the product sit on the page where the buyer is already deciding, not in a cart drawer they'll never open. Our guide on using product bundles to raise average order value on Shopify walks through how we set those tiers up.
Amazon sells a unit. Your page can sell a solved problem. The second one costs the buyer more and makes them happier.
That's the whole trick, and I'll admit it took me longer than it should have to see it. I spent years trying to shave cents off landed cost and fulfillment fees. The lever that moved profit 10x was the size of the cart.
Why didn't a $63.40 ad cost sink the Shopify side?
Nobody puts this line on the sales deck, so I'll put it here.
Advertising went from $5.99 per sale on Amazon to $63.40 per order on Shopify. That's $57.41 more per order. On Amazon the buyer walked in already shopping. On Shopify every visitor is one you went out and bought, and "owning the customer" doesn't make that invoice any smaller.
Now watch what happens with the two carts.
Put that $63.40 against a $29.95 Amazon-sized order and you've lost money before you've shipped anything. Put it against a $177.75 order and you clear $78.87. Same ad cost. Same product. The only difference is what the page sold.
After paying for ads and inventory. Real client numbers from /results, not typical results.
$78.87 divided by $7.73 is a little over 10x. And the fee saving contributed $2.99 of that per unit. The rest is the fat order.
I'm Ishan Soni, and at RevenueFlows AI the number we build every page around is revenue per visitor: conversion rate times average order value. Run the math on a hypothetical page converting 2% of visitors. At a $29.95 order, that's $0.60 per visitor. At a $177.75 order, the same 2% is $3.56 per visitor. Same traffic, same ad spend, and the page is suddenly worth paying to send people to.
What does $78.87 per sale mean in sales per day?
Here's the math, and it's the same logic as the calculator under each case study on /results.
Say you want $1,000 a day in profit from this one product.
- On Amazon at $7.73 per sale, that's 130 sales a day.
- On Shopify at $78.87 per sale, that's 13 sales a day.
Read it again. 130 packages or 13. Same $1,000.
Flip the calculator to revenue and the gap is still there. $1,000 a day in revenue takes 34 orders at $29.95, or 6 orders at $177.75.
Thirteen orders is thirteen boxes and thirteen chances of a support ticket. If you've never worked out your own number per product, our post on profit per product on Shopify shows how to pull it, and how to calculate landed cost covers the line most sellers get wrong first.
A skinny order needs volume to survive. A fat order needs a page.
What does this rodent repellent brand case study not prove?
I'd rather you argue with the numbers than get sold by them, so here's what they can't carry.
It doesn't prove fees are the answer. The platform fee dropped $2.99 per unit. Ads rose $57.41 per order. If the fee cut were the whole story, this product would have lost money on Shopify.
It doesn't prove you should leave Amazon. The Amazon column is the baseline the whole comparison stands on. Keep the reach. Build the profit on the page you own. Our page on why Amazon sellers are moving their winners to Shopify covers the fee side in full.
It doesn't prove every product does this. A $49.95 product turning into a $177.75 order needs a buyer with more than one place to protect, and a page built to sell that. A product bought once and never again runs on different math.
And it doesn't prove the Shopify column recomputes line by line per unit. It doesn't, and I've told you why: ads and profit are per order, the rest is per unit. The first product in this series, a $17.95 animal repellent, has the same shape, and the full Amazon to Shopify case study on that one is worth reading beside this. All three Amazon products, plus the bedding brand, sit in our ecommerce case studies with real numbers.
How is AI changing the move from Amazon to Shopify?
The old reason sellers stayed on Amazon was never the fees. It was the page. An Amazon listing is a template you fill in. A Shopify product page that has to sell a $177 order from cold traffic is weeks of copywriter, designer and developer time, and most sellers never start.
That's the part that changed. Our homepage puts it in one line: "Drop in any product URL, the AI writes the copy, designs the images, and builds the page, in less than 15 minutes." You feed it the Amazon listing you already have, the reviews, the one-star complaints, the photos. What comes back is a page whose job is a bigger order.
The page still has to be written for a Shopify buyer who has your Amazon listing open in the next tab. Our guide on writing a Shopify product page for Amazon shoppers covers what that buyer needs to see before they trust a store they've never heard of.
What to do next
Take your best Amazon product and answer one question: how many of these does one buyer actually need? If the honest answer is more than one, your Shopify order has room to get fat, and the only thing standing between $7.73 and $78.87 is a page that asks the right question.

Frequently asked questions
How did a $30 rodent repellent reach $177 orders on Shopify?
The price moved from $29.95 to $49.95, and the page was built to sell a bigger order instead of a single unit. The average order on Shopify landed at $177.75, about three and a half times the new sticker price, so each checkout carried its own ad cost and still kept $78.87.
What was the net profit per sale on Amazon versus Shopify in this case?
$7.73 per sale on Amazon and $78.87 per sale on Shopify, after paying for ads and inventory. That's a little over 10x, and almost all of it came from the order getting bigger, not from fees getting smaller.
Why was advertising so much more expensive on Shopify?
On Amazon the buyer is already shopping, so ads cost $5.99 per sale in this case. On Shopify you pay to bring every visitor in yourself, which came to $63.40 per order. A $29.95 cart can't carry that. A $177.75 cart can.
Does moving an Amazon product to Shopify save enough in fees to matter?
Not on its own. The platform fee on this product fell from $4.49 (15%) to $1.50 (3%), a saving of $2.99 per unit. Ad cost rose by $57.41 per order. The move only paid because the order grew from $29.95 to $177.75.
How many sales a day do you need for $1,000 in profit on each channel?
At $7.73 per sale on Amazon, 130 sales a day. At $78.87 per sale on Shopify, 13 sales a day. Same $1,000, one tenth of the packages.
