Otherwise it has been the deal of the day at Amazon a few times for $20 and I'm guessing you could buy it used on CAG trading forum for $20 or less too.
If you're not in a hurry you could wait for a B2G1F sale at TRU, CC, or BB. I got mine from BB that way last year around when it came out (B2G1F on Touch Generations games at BB)
