Crazy, I know...

A friend's company will be exhibiting at a trade show which features a Transformer on the flyer/program, so they decided to giveaway Transformers to the 1st 400 people that visit their booth. They want them sealed, and as cheap as possible. I told him worse case scenario, he could buy them at retail for $6 each from Kmart and I also told him to call Hasbro AU directly.

Does anyone else have any other suggestion as to how to acquire such a quantity in a week?
