I've been to a Trader Joe's once. All remembered is bulk food like stuff.
Oh, okay.
It must be the equivilant to other bulk supply stores, like the southeast has Sam's Club (it's supposed to be like a sister store to Walmart), and the northeast has Costco.
I'll tell ya what though, I RULLY got a great bargain from Sam's Club a few months ago... I'm ALWAYS running out of batteries, so I snagged a 48-count pack of AAs for like $15. The problem is almost everything electronic in my room runs on AAs: cable remote, TV remote, CD player, digital camera (it takes disposable batteries instead of a re-chargable one), plus other rooms in the house that has remotes and such take AAs too, so that eats them up as well.
