If you are lucky enough to have a CostCo in your area, go ahead and go. Went there today, and they had a nice deal on Thumbdrives. You can get 3 2Gb Sandisk Retractable USB Cruizer Drives for 48 bucks. (16 dollars a piece). So it's slighty cheaper (or about the same as) Newegg.com's prices here. Except, you get 3.
I think it's a good deal, at least comparable. Hell, I remember spending 89 dollars for my 512 Mb thumbdrive back in the day, and that was a steal. Now 2 Gb ones are McDonalds money. (Reference: McDonalds money means "roughly the same as it would cost my family to eat at McDonalds"
