They're a little too late to the punch. If they had done this in early January, they would have done pretty well for a few months. But now that the supply is swelling to ridiculous amounts at most retailers (especially the older ones), expect Skylanders to be in a "bin" at your local GameStop pretty soon.
I saw a Legendary Trigger Happy for sale at Gamestop today for 19.99 (17.99 if you're a member of their points BS). WTH are they smoking? Yeah... they totally missed the profitability window by about two months...
I went back today and the same GameStop had raised the price on the SAME Legendary Trigger Happy to 23.99. I started chatting with the clerk and I told him that every TRU I've been to has pegs FULL of Legendary Trigger Happy that haven't moved in weeks. He was doubtful, and his only counter was "Isn't he the elite version of that guy?" I said it didn't matter because anyone can go to TRU and get this figure, unopened, for $10. Nevermind that the trade-in figs they sell don't include the card/sticker/webcode.
Someone at GameStop needs to be brought down a peg...
They need to put little notes like "fully powered up" on pre-owned figures. That would make it worth that price. IE if somebody went through the trouble of going through and doing all the Heroic Challenges & powerups available for a character.
Though the question does occur, can you claim ownership of any Skylander that you put on the Portal of Power?
The problem with Gamestop - and the reason why their irrationally inflated prices often work - is that they only need to sell that preowned item ONCE and they've won.
And no matter how much I'd like to believe otherwise, they'll ALWAYS find a clueless parent or a desperate 10-year-old that will purchase the figure regardless of savings or availability.
For instance, my local Gamestop had three preowned "Adventure Pack" sets - just the figures in plastic bags, really, and were charging $19.99 for each set. (One of them didn't even have all the pieces!) I went back a few days later and they only had one of the sets left. This is despite the fact you could literally walk three doors down, go to Target and buy the pack NEW for the same price.
