didnt know where else to post this :S but since I'm in the TP2 area the most... lol
DailySteals® | Online Deals | Deals Site : DailySteals.com has a good deal for the 16gb class 4 sd cards today. I bought one for $13 (it's $8 but has a $5 shipping cost)
I can't comment on the quality, its from a brand I havent heard of, but meh, it's cheap enough that I bought 1 to try out lol
