Yeah, I've picked up a bunch at Target over the last few years.
I was in KMart the other day with my son. They've had one of last year's sets on the clearance isle for a month or two (its the one with Han on a TaunTaun, a couple Rebels and two Snowtroopers), but never quite cheap enough where I was willing to bite (I already had the set, but I could use a couple more troops and Luke needs a TaunTaun too...). So I scanned the price ($15 something...) and my son HAD to have the set. He's not big into LEGO, so I tried to show him a few other things he might want instead (Imaginext plane or a Megablocks Dora set...), but he had to have the LEGO Star Wars set.
I had a hard time convincing my Wife that it really was my son's decision, but I couldn't help but be proud!
