The pegs are at least half full of singles, I see about the same amount of Vehicles at Target as I do at Wal-Mart and you're right about the comic packs
Now to put some things into perspective, I did searches on a few store websites for "G.I. Joe" Here's the results:
Wal-Mart: (20 Items)
Comic Packs up to wave 4
Vehicles
DVD sets
Sigma Six items
The Story of GI Joe DVD
All of which, apparently, aren't sold in stores
K-Mart: (2 Items)
Wave 1 Comic packs (No Snake-Eyes!)
Sears: (2 Items)
Wave 1 Scarlet/Hawk Comic Pack
G.I. Joe Ernie Pyle DVD
Kay Bee: (9 Items)
Wave 2 & 3 Comic Packs
Viewtiful Joe for Game Cube, PS2 & DS
Toys R Us: (31 Items)
Single Figures up to Wave 7
Vehicles
DVD sets
12" figures
Comics up to wave 3
1 Star Wars Comic Pack
Star Wars, Transformers, and G.I. Joe Comic Book Gift Set
Target: (1 Target match, 56 Amazon.com matches)
Sigma 6 Party Supplies
OK, Sure Target.com sucks the worst, but other than TRU and Wally World, it looks like they all suck to me
