I used to have a Sam's card, but a few years ago I decided it wasn't worth the extra yearly fee to buy things in bulk. I was only going to eat the samples, which is not a good habit. I bought stupid things like a package of pot stickers for $8 that were so gross by the last one - I'll never buy those again.
We are a family of 2 + dog, so we don't really need things in bulk. However, I went the other day because I wanted to stock up on the big bags of DD coffee. I managed to stock up on $120 worth of bulk things while I was there - including this guy:
A monster jar of animal crackers. Just so you can see how big it is, it's almost the same height as my 27lb pug. And in case you can't read it, that's a 4 lb jar of animal crackers.
