Not sure if anyone has already found this for less, but this is the cheapest I've seen it. Both versions of Bayonetta (PS3 & Xbox 360) for $19.96 + $2.99 shipping. Although there may be coupons out there for free shipping.
Too late Richard & Sons! You had your chance but ran out of copies a while back so I went to Amazon. She was there when I needed you the most. I finished it, platinum-ed it, and enjyed it. Muahaha! Definitely worth picking up. Now gimme Ninja Gaiden Sigma 2 for $19.96 pretty please!
