I was watching them alittle while ago and nobody bid on them. I had a friend that wanted to get them, but shipping was $200 to Pa. Starting bid was only $1. Here's it's old item # 170019868066. In that sale they had 2 kits for sale. Then they wanted buy it now for $400. Maybe he did miss a "0" in the price, but isn't the sale a legal binding contract? Not your fault that they mispriced it!
Ebay makes you read thru a little song and dance that says basically clicking to continue signifies a contractual obligation. Not sure exactly how legally binding it is, but it does use some pretty distinct language.
