You can get an Amex CC through Costco that doubles as your membership card, so there's no Costco membership fee plus there's no annual fee on the card plus you get a rebate on your purchases, something like 2-3%.
Anyhow, there's a BJ's opening up right down the street from me, maybe I'll check out their grocery section...and of course, I'll check out the iPaq in keeping with the spirit of this thread.
