$17-28 for a single TVC figure isn't likely to pull in many kids, so I can understand why they need more options for consumers that aren't 40-year-old men. I know this is a radical notion to some hardcore collectors, but I think they need to do more to get the younger generations into the brand, rather than catering to us, as adults. Personally, I would cap TVC at $15, Retro at $10, and Epic at $8. The higher the prices go, the fewer casual consumers will buy these products, they'll just wait for sales or clearance.
As for Epic sales, it's hard to determine based only on the three of us in this thread, lol - over on RS, there is more chatter surrounding collectors buying these, as well as some people seeing them move at retail, as I have. I think it's all about distribution and stock levels though, if an area is flooded with any product, including TVC and TBS, they will likely pegwarm. They're showing up at Target now though, so maybe the sales at WM and Amazon were significant enough to warrant Target wanting to stock them as well...
