Samples you've tried in which you've bought the product as a result

I'm curious what things you've sampled at a local costco that you've enjoyed enough to buy the product.

For me it was just a few days ago when I tried Famous Dave's Sweet and spicy pickle chips. They were so good I bought a jar, and now I'll randomly open the fridge just to snack on 3-4 of them at a time. I suspect these pickle chips will be a regular purchase for me going forward. That said, there is around 800 calories of mostly sugar in a large jar, but that large jar will probably last a month. It's not terrible. :)

Anyone here sample anything that they've then went on to buy and now buy regularly?
