hell yeah i will definitely go to costco just to buy that one 32oz package of smoked pulled pork from the cold/deli section and get a hotdog on my way out. the pulled pork is only fractionally more cost effective on a unit price / per pound basis, but i will drive thrice as far to buy it so i can get a hotdog and a drink on my way out XD
I'm not saying the premade pulled pork isn't good, but if your idea of barbecue from Costco doesn't include the incredibly cheap prime-grade brisket and smoking it yourself, you're doing it wrong.
My local Costco always gets some amazing avocados. Maybe I'll go there on my lunch break today and pick up a bag, and get myself a hotdog on my way out.
You can get cafeteria items, prescriptions, and optometry services without a membership, too, last time I checked. Just tell the greeter why you're there.
