Even though there are tons of H&V figures on the pegs at your local store, they still may be selling quite well...
I think back to the "Hulk Hands" from a few years ago. Those damn things were in HUGE numbers everywhere I went. I would have sworn it was the worst selling toy ever based on how many I kept seeing, but they ended up being the #1 toy seller that year. Sure, the local TRU had 100 on the shelf, but they were selling 10 pairs per day and stocking 20 every other day.
Out of curiosity on the H&V, I started checking my local Target every other day. Despite the fact that each day there were 20-24 figures on the pegs, the actual figures on the pegs kep changing. One day there would be Pilot Obi-Wans and Shocktroopers, the next they'd be gone replaced by Yoda and Vader and Droidekas. Then, the next time, the Yodas would be gone and replaced by something else. Etc, etc, etc. The mix kept changing every few days.
As near as I could tell, that Target stocked at least 7 cases (84 figures) of H&V over a 2 week period. The whole time though there were 20-24 figures on the pegs. If you weren't looking closely at the content of the pegs and just seeing the full pegs, you would think they haven't sold anything in 2 weeks, when really they had sold about 85-90 figures.
Even if only half of the Targets (650 out of 1300 stores) are selling the H&V as well as my local Target (let's say 40 figures per week), that works out to a crap load of H&V figures being moved each week (nearly 26,000 H&V figures sold each week). And that's just Target and not even counting TRU and Wal-Mart!
Maybe they really are selling better than we can see...
