I tried it for a year. Not badass for me, even sharing with my boyfriend. Partly it's the fairly long drive (outskirts of city I live in). A lot of the prices weren't that great--most of my staples were the same price or cheaper at my regular grocery store, if they were available at all. A lot of their famous good prices are for things I really don't use in bulk (for example, I only fill my gas tank once every month or two, and it's not that big of a tank), so the overall savings don't add up much. And (as with most stores, I suppose), I really didn't want most of the stuff they had.
I did love the sliced almonds, sliced Tillamook cheese (though I wish they had one of the sharper flavors), and a few other things. We got a nice sale on V8 (which I did drink), motor oil (which I did not), and a couple of tools during our membership period.
They also had a few things I loved but never bought because they are evil, expensive, or both. One I remember is these lace cookies: kind of a dark-chocolate-covered toffee-flavored gorgeous delicious cookie I've eaten at parties. Another was a crazy-fancy bread that looked like they rolled out dough to the square footage of my house and then added delicious things like ground nuts, seeds, and/or spices, and folded it up somehow into a bread loaf shape and cooked it. It was about $10, totally worth it for all of that work, but I really don't need luxuries like that when cinnamon toast is almost as good and can be made with whole-grain bread.
I prefer:
* HEB (a regional grocery store) for ordinary groceries and bulk items,
* Wheatsville (a local food coop) for hard-to-find things like spelt pretzels (they have fiber!), non-homogenized milk, non-GMO corn tortillas, and bulk organic chocolate chips,
* Whole foods for some of their 360-brand stuff and organic blue corn taco shells,
* Target (NOT online) for vitamins and for stuff I don't feel like researching prices on (there's a Target in walking distance of my house)
* Amazon for other various things
* Reebok (online) for sneakers
