I think there's slight truth to both points... Darth Ice points out the "vintage" figures, and I think that's a valid point that Target does try milking something as best they can for the most they can, which simply takes them out of competitiveness for me... The same will apply to the comic packs where they seem like they'll be a full $1 more than Wal-Mart, even if WM price increases... At least in my neck of the woods that seems to be the case as I saw them for $11.99 compared to a possible (haven't seen comics at WM in ages) $10.88 price at WM...
The price increase isn't a shocker though, like Jeff said. It's just disappointing to see it jump more than it was supposed to jump at Target... They dance on the K-Mart realm of pricing at times, depending on the item.
The other disappointment is that, while the comic 2-packs are often neat, the price was what made them so to an extent. Villie as a figure is cool at $5... At $6 he's dropped from cool, to nice. If he jumped to $7, he would be disappointing I think.
That is true across the comic line in general though... Dark Woman is the Het set stinker, and she wasn't great to begin with IMO. So the price increase kind of knocks her down a few pegs as a figure. Sets like the Commando/SBD will still be cool, Obi/Alpha are still a value IMO, etc. There's a fine line though, where my utility for the dollar has been maximized with some of the sets I think. It's the accounting experience in me I guess that makes me view things so intricately, and with such scrutiny.

Anyway, basics are still $5.88 at WM here, so I'm still happy there... I hope that doesn't change. I stomached the $7 price all year, but the drop at WM is just great while it lasts. Kind of makes up for the rest, and it's just ideal for getting the extras as that $1 mounts up fast.
