My children LOVE these! My 6yr old son will play for hours & I mean hours with these. He has told us he needs more and I found an auction on Ebay that sounds like a great deal. It is for 750 of them plus the case. The bidding right now is at about $16.50. I would like to win this but how much would be to much? What would you set your limit to? The shipping is just $5.
