is a costco membership worth it? it seems like it, but $45 is a lot of money for me. if someone who has a membership could tell me some average prices on stuff that'd be awesome. the things i buy the most is: pepsi and diet coke (in cans), brown rice, pasta (whatever kind is cheapest), a LOT of vegetables (mostly fresh), canned pasta sauce and tomatoes, tofu, soy sauce, fruit juices (when we can afford it). things like that. any input is more than welcome! and yes, it's just me and my husband, but he's on testosterone supplements (long story), so when those shots has taken place he eats for two. or three. it's ridiculous, really. so yeah. bulk sounds like a good idea. paying $45 not so much. costco, yes or no?
