I have seen quite a few posts about Skylanders, the Kaos trap and the sets.
I just saw this on Ebay and wanted to share. It is the Dark Edition starter pack fro Xbox360 (the one which comes with the Kaos trap), being sold for a reasonable price - £77, on buy it now, unlike the ones going for £140 +.
Not sure if anyone is still looking, but in case you are: www.ebay.co.uk/itm/xbox-360-SKYLANDERS-Swap-Force-Dark-Edition-Starter-Pack-NEW-SEALED-Microsoft/191435846855?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D28111%26meid%3Dfbaef5647a7c43f59b95ad835f3b909d%26pid%3D100005%26prg%3D11472%26rk%3D2%26rkt%3D6%26sd%3D261692914619&rt=nc
