I get some stuff at retail (various Wal-Marts, K-Marts, and Krogers) - but I don't go to any of those places very often (and even if I did, I probably wouldn't ever score much from 'em), so I order most of my figures from online retailers.
Try to stick to the retailers, but as recent luck would have it, may have to move to on-line. Finding anything at retail post-christmas is like trying to do dentistry with a sledge hammer. . . effective, but painful as hell.
