Most sourcing time goes into looking at products that were never going to work. Over the years I've found two signals that cut that down more than anything else.
Signal 1: sellers you respect just added it
When a seller who does well adds a product to their storefront, they've usually just done the research and decided it's worth buying. When several of the sellers you watch add the same product, that's a much stronger hint.
In the last 14 days, the sellers I watch added 275 products. 7 of them were added by two or more of those sellers. That is a list I can actually work through.
Signal 2: you just got ungated
Amazon's gating changes all the time. Re-check the brands you're gated in and some of them open up. Those products are now available to you, and to fewer sellers than everything else.
Over the last three weeks, 1,510 products became sellable for me. 200 of those sell 100 or more a month, according to Keepa.
Where the two overlap
Products with both signals (other sellers just added them and you just got ungated) are the ones I look at first. For me that is 14 products this week instead of about 1,800.
How I rank the rest
Opero3P's Bob Sourcing puts it in one list (Sourcing → Storefronts). It ranks products up for:
- more of your watched sellers adding them, and starred sellers counting extra,
- being newly ungated for you,
- coming from brands that already make you money,
- Keepa monthly sales.
It ranks them down when Amazon holds the Buy Box most of the time, when there are already 15 or more FBA sellers, or when the price keeps dropping. Anything you're hard-gated in or already carry is left out.
The score ranks what to look at. It isn't a profit forecast: that depends on what your supplier charges. One click on the 🚀 opens a Google search for the product and its Amazon page side by side, so finding a supplier is the next step, not a separate job.
FAQ
How do I see what other Amazon sellers are adding? Save their seller IDs to a watch list and check daily for new products. Opero3P does this every morning and shows only what each seller added since the last check.
How do I know when I've been ungated in a brand? Re-check gating regularly on the brands you're gated in. Opero3P re-checks gated brands weekly and lists what opened up.
Is a product other sellers just added always a good buy? No. It's a reason to look, not a reason to buy. Check the Buy Box history, the number of FBA sellers, and your real cost first.
