There is so much you can do there. Of course, you can shop--although you need to be a member and you have to buy large size packages. But aside from the obvious, there are other advantages to spending a few hours there.
One nice thing they have is demos of some of the food products they sell. Not only are they tasty, but they introduce you to things you might never try if you had to buy a large package of it. Who is going to buy a $10 package just to get it home and find you don't like it?
Then, if you are still hungry, you can go to the little "restaurant" and have a quick meal. There is pizza, hot dogs with a drink for $1.50!!, frozen yogurt, and other food. It is quite economical and good.
I realize that this is not a place for everyone given the membership fee, and the size of the product packages, but I love it, and obviously, so do many other people because it is always crowded.
I must add that they carry all kinds of merchandise, from soup to nuts, to furniture, appliances, eye glasses, etc. etc. You can also buy online.
