I saw three more copies at the Fred Meyer across from Lowes in town. Obviously the 50% off coupon isn't working any more or I would have picked them up. Anyone else in the Portland/Vancouver area might want to run over there though. (hint hint)
While the sale was still on I grabbed Astro Boy, Contra, and Space Channel 5. So far I've only opened Astro Boy and it's pretty fun. Hard if you don't power-up the right thing at the right time, but fun.
