4 Macs , 6 Diddys & too many Zeldas to count left at TRU in Niles, IL as of 5:15 after I bought a Mac & a Diddy.
But one of the remaining Macs has the foot out of the base.
As an aside - has anyone tried/succeeded in removing the plastic support blocks on theirs? I hate the look.
Not sure there's a "number of overall items" limit, but there is a limit on the number of one item (ex: Xbox 360 Mass Effect 2) you can trade in, and any trade-in is limited to a max. trade-in value of $750.
