<< <i>There's quite a few of those AT ikes in today's teletrade sale- and they're all currently going for between $30-$40 dollars with 2 1/2 hours left. I wanted to pick one up for the cost of the grading fee.....
How much you wanna bet those are "reserve bids", and none of them actually sell?
That would be interesting to know. I'd like to hear the whole story about those ikes- there's 7 of them, and I wonder who the proud owner is?
