I know Costco can be overwhelming, or suck you in (please tell me that happens to others too?).  But there is a lot of value when buying in bulk and it's how we keep our food expenses pretty low.  If you have a 2nd fridge in the garage, it's even better.  We store all the duplicate items in there + beer :)  Here are some of my personal favorites from Costco.  At this point we get all our grains, proteins, veggies and dairy from there.  I get some fruits there and some from HEB, along with my all time favorite pizza crust (pictured below).  We freeze 1 of the 2 loaves and proteins as well.
