I've found both Reb sets at both Ross and TJ Maxx lately actually. Also the Imp. Evolutions set #1, Fetts, Padme, and Force Unleashed. I've been seeing those (plus AT-TE's for $50) for the better part of December so I've been steady in stocking up when I have an extra $20 or $30 to plunk down on a couple sets.
They were a pleasant surprise for that price... the Reb sets are especially nice, and especially the one with the B-Winger in it. It's a shame they didn't deliver the normal height X-Winger sooner in a way.
