My experience is that warehouse clubs CAN be worthwhile, but you've got to do your research. Until recently I could get photo inks for about half of the street price from Sams Club, but now they're at about 85% of the street price; still worth it, but I need to keep an eye on the price. Years ago I went to Costco (then PRice Club) to buy a TV and got the same TV for less at Circuit City.
