I've recently purchased a 30G IPOD from Sam's Club for $267 that includes video, photos, etc. and came in a box shaped like a cube. A friend also wanted to purchase one but before she could, Sams sold out. I went with her to Target where she bought the same 30G IPOD for $299 but in a flat black box. Is there any difference between these two systems and how do these units relate to either the 4th or 5th generation models?
