Are October Deals Worth Reselling?
Prime Big Deal Days takes place October 6 and 7, 2026. It could turn up products worth researching, but a great deal for a shopper is not always a great deal for a reseller.
Say you see a product marked down from $40 to $20 during Prime Big Deal Days. It’s tempting to buy a few and resell them later, right? But before you fill your cart, use these five checks to find out whether a deal has real potential.
1. Can you sell the exact product?
Start in Seller Central, not at checkout. Find the listing for the exact item you want to buy. Check the size, color, model, and pack count.
Then confirm that your account can sell it in the condition you plan to list. Some products and brands require approval. You should also be able to document where your inventory came from if Amazon asks.
If you cannot confirm your eligibility, let the deal go. There will be others.
Pro Tip: Use the Alerts panel in SellerAmp SAS to flag possible restrictions and IP concerns before buying.
2. Will the resale price hold up?
A product selling for $28 today might not sell for $28 after thousands of shoppers see it on sale. Other resellers may buy the same deal and compete for sales once the event ends.
Check current competing offers and the product’s price history. Then test a less exciting scenario: Would you still make money if you had to lower your price?
Pay extra attention to seasonal products. A Halloween item has a short window. A product people buy throughout the year gives you more time if it sells slowly.
3. What is your profit after all the costs?
The gap between the deal price and the resale price is not your profit. Amazon fees, shipping, supplies, and returns can take a big bite out of it.
Here is a simple example.
| Item | Amount |
|---|---|
| Expected selling price | $28.00 |
| Prime deal purchase price | −$12.00 |
| Estimated referral fee | −$4.20 |
| Estimated FBA fulfillment fee | −$4.80 |
| Estimated inbound shipping and supplies | −$1.20 |
| Allowance for other costs | −$1.00 |
| Estimated profit | $4.80 |
That $16 difference between the buying and selling prices has become an estimated $4.80 profit. A small price drop could wipe it out.
Run the exact item through the Profit Calculator in SellerAmp SAS, and add any costs the estimate does not include. Timing matters, too: Amazon says its 2026 US holiday peak fulfillment fees apply from October 15, 2026, through January 14, 2027. If you expect to sell during that window, check the applicable peak rates.
4. What is your plan for fulfillment?
Decide what happens after you buy the product. Will you receive and inspect it, then send it to Amazon FBA? Or will you store it and ship customer orders yourself?
Factor the time and cost of that plan into your numbers. If you are considering having another party ship an order directly to your customer, read Amazon’s drop shipping policy first. Amazon requires you to be the seller of record and to meet its requirements for packaging, paperwork, returns, and customer service.
5. How many units can you afford to get wrong?
This may be the most useful question of all.
A countdown clock can make a deal feel urgent. It cannot tell you how quickly the product will sell at your target price. Set a buying limit before the sale starts, especially if you are testing an item for the first time.
Write down your minimum acceptable selling price and what you will do if the item sells slowly. If the deal only works when everything goes perfectly, it probably is not the right buy.
Your Prime Big Deal Days arbitrage checklist
Before purchasing inventory, ask:
- Can my account sell this exact product and condition?
- Does it match the listing in every important detail?
- Can I document where I bought it?
- How many other sellers are competing?
- Would I still profit at a lower selling price?
- Have I included the fees that apply when I expect it to sell?
- How many units am I comfortable holding if it sells slowly?
Prime Big Deal Days is a fun time to hunt for opportunities. The trick is to stay curious and selective. Check the numbers, know the rules, and be willing to skip a tempting discount. The best arbitrage buy is one that still makes sense after the excitement of the sale wears off.
