I've never been to costco (closest one is a bit of a drive), but you sure hear nothing but good news about them.
Cheap gas:
They treat their workers better than a walmart etc., and they're profitable too:
Let's see what else have I read about costco.. something about a few of their "kirkland" brands, I didn't know about the walnuts dino but I've read something about they have some really good stuff under that store label. And the strategy is to keep people coming in for that stuff. Like a loss leader.
I'm sure they don't treat their workers great (
) but I do like Dollar Tree, incidentally. Saves me a heck of a lot of money. All my toiletries, detergent, household stuff, cleaning stuff -- why pay more when you can get it for a dollar. There's just so many things that would cost $4 or $8 at a walmart and you can get at the darn dollar tree for a buck.
