This has made me crazy for years. I'm still seeing sections filled with the TPM wave, and I have not seen a single figure past that.
In my area, most of the problem has come from the figures from Wave 1 carried forward into the BluRay Deleted Scenes wave.
For example - 1 Toys R Us is sitting on a whopping four different figures - Qui Gon Jinn, Naboo Trooper, Quinlan Vos & Queen Amidala.
Now I recognize that the TWO Queen Amidala figures are from their shipments of Wave 1, but this store got hit pretty heavy with the Deleted Scene wave - I would say at least 7 cases all at once, and I'm sure that those cases contributed to the 8 Quinlan Vos figures, 7 Naboo Guards and 4 Qui-Gon figures that are also on the pegs.
The problem is that when you add them all up, it leaves you with 21 figures on the pegs - almost two full cases worth, and I'm sure ultimately the reason why this store hasn't gotten in any more Vintage figures since that Wave 2 push back in February.
From a business stand-point, I agree with any store manager looking at the bottom line and saying "well I have 21 Star Wars Vintage figures in stock, why should I order more?"
I have been tempted to "help" with the situation at this store and acquire more Naboo Guards - but I already have eight open, how many more do I really need? Now if there were great head swapping opportunities with the head on this figure - the Rebel Honor Guard, the Rebel Fleet Trooper, Endor Rebel Trooper, Imperial Navy Commander, etc... then maybe I would be compelled to do so, but Hasbro has yet to learn how to make it so they have a universal neck joint for their human figures yet - and that is a totally unrelated discussion...
I know it sounds horrible - but at SDCC and CVI this summer, I really hope Team Dimwitz at Hasbro are there and get their assess handed to them by the fans/collectors...
