I think price is a sound argument... Why put as much into the pricey line when the other one seems to sell steadily better, and for less money? Hell, at $6.50 at WM, my stores have been blowing through legends stuff consistantly, and they had decent enough sales before because new stuff that sold out would turn up. I keep seeing new BD 2-packs out on the pegs almost every time I'm in now though, and that's sometimes 2 or 3 times just on a weekend, and I pick them up if it strikes me... And yet more turn up, so I know they're continuously putting out new Legends cases... I don't keep up with CW figures as much, but I know for a fact that all the Embo's, Cato Parasitti's, and the like are drying up here. All the female Jedi figures are now long gone and you can't find a battledroid around either. I used to see Embo like fly dirt around here, and he's largely gone now too. Kind of shocking.
Legends though, I see fewer and fewer Phase 1 Clones, Snowtroopers, etc. Then I'll see more, then it'll be gone... wash, rinse, repeat.
But here KM's pegs are bare. My stores have 2 or 3 Vintage figures only (one lone Woof hangs out at my local KM. He makes me sad), and they're getting nothing new in. Like I said, this is pretty routine for K-Mart though, in April... They always cut back right at this time of year, especially on a line like SW. They've got a good many Clone Wars, Lock's, and Legends though.
Target has 1 Vintage figure on each peg, but they've moved a lot of Legends and Clone Wars stuff it seems, and I think their sale will probably help them. On the vintage pegs it's either 4-LOM, Dengar, or CC Pilot pulled out to the front, and not a single other figure anywhere. Each peg has just that one vintage figure. It's comical almost. However with this sale, the clearancing of the Geonosis 2-pack stragglers... I'm betting more stuff may be on the horizon for Target, plus possibly a toy dept. reset.
And like I said, WM has been moving Legends/CW stuff pretty steadily, and other than the Phase 2 White Clone, a couple straggling Wave 1 figures, a handful of Sandtroopers, and maybe a couple Obi's/Ani's, everything Vintage is moving too, though there's not nearly as much. The only figure out of that whole tribe I'd call the ultimate pegwarmer then is the white Phase 2 Clonetrooper then, which of course a new one turns up here and there depending on what case is opened (and I keep seeing Vin wave 4 - 6, even at the same stores and out of order). The 212th Clones are all selling though, Sandtroopers aren't nearly as pegwarmery as they used to be, and when a new case of anything from Wave 4 to Wave 6 is opened, it generally sells out save for that White Clone if he's in there.
But to put it in some perspective, my nearest WM had a ton of the pre-pack shippers on an endcap, not even on the main aisle, and they sold out of EVERY figure in them practically, in about 1 week. What was left got moved to the regular pegs, and almost everything that got moved is gone because this store is down to no Anakin's and 1 or 2 of the new Obi-Wan, and nobody else that was in those sets... That's a ****load of toys sold in a week when you think about it, and that wasn't even counting the stuff at the normal area. I mean those pre-packs were hard to even find at my WM because they were facing the wall. They were picked clean though, lickity split.
