The PNY CS900 is reportedly being clearanced out of Staples in stores, YMMV. It's not advertised online, and clearance tags weren't always present. When tags were present, the prices were incorrect.
120GB for $14.46,
240GB for $22.46,
480GB for about $33. —- $34.46
I bought 2 120GB and 2 240GB last night in Overland Park, KS. I bought another 240GB last week to test.
