FWIW, it can be hard (at least it was for me) to find something for the Small Business $!0 offer. I didn't see any immediately obvious way to search within the eligible items, and it seemed as if I could spend a long time having to browse through their various categories to find something I truly wanted and could use and wasn't just thinking about buying for the offer. Then in the actual picture of groceries used for the icon used to link to eligible items from food companies, I noticed a company I have already bought dried lentils and dried beans from in the past, Palouse Farms.
So I spent about $14 re-ordering some more lentils, only a little bit sooner than I really need to

, and have verified by the amazon.com/primedaycreditcheck link that I already have the $10 credit. Nice win - to be able to order something I already know I use and like and still get a credit on it.
So, if anyone else wants to check out bulk (multi-pound sacks) lentils or beans or flour and get the credit, try the Palouse Brand Store:
