This deal has ended.
Likely for today only, Amazon has Prince of Persia for either PlayStation 3 or XBox 360 on sale for only $39.98. This is an impressive price, as this game was just released and almost impossible to find discounted. I've played earlier versions of this adventure game, and can attest that they're incredibly well thought out. Shipping is free with no sales tax (except NY, KS, KY, ND, WA).
