Costco produce ordered online can be a bit hit or miss, unfortunately. You know how when you shop at Costco, it's usually better to dig down a layer with produce since the top box always has everything that's been rejected by someone else? I'd guess, based on our mixed success, that some Instacart shoppers just grab from the top of the pile. We've had some shops with bad produce, but most have been great.

What sucks is that if you return it to the warehouse, you don't get the full price back because of the Instacart markup; on the either hand, you can sometimes return things at a net profit because of Instacart offers (like the $10/mo. Executive Members thing.)
