Some more whackiness at on of my Targets. Only polybag sets I saw were the mini X-Wing, a huge pile of police boats (30002, according to BL it is a 2009 set), and the Atlantis Octopus (30040).
The X-Wing was clearly marked as an X-Wing, and the price was $2.99.
The bin holding the police boat sets said "Star Wars/TS3 Asst" and was marked $3.99. I didn't buy any but I assume that's what they would ring up for, since it has a minifig.
The Ocotopus was in the checkout lanes, hanging from tags that said "Star Wars/TS3 Asst" and marked $2.99
The Octopus rang up at the register as "Star Wars" for $3.99. (!?) They gave me the $2.99 price though since it was right there for the cashier to see. I don't recall if others reported the Octopus as $2.99 or $3.99?
At any rate, I think stores (and LEGO) are figuring out that there is plenty of demand for these polybag sets around christmas, there seems to be both a greater variety of sets this year, as well as a larger supply at individual stores.
At Target so far we have seen polybag sets for:
Mini X-Wing, Racers, Police, Fire, TS3, and Atlantis (6 different sets!)
At TRU there is also the Imperial Speeder Bike and I saw a bunch of Creator snow men recently as well. (30008)
