I know not everyone has a KMart near them.  There aren't going to be any of the highly sought after cars, but it still might be better than waiting for the ebay listings and buying them separately.  It'd be $21.22 (exact cost for 5 cars and tax) plus shipping and you could complete the promotion on your end.

For international folks, it looks like the promotion will not ship overseas.  But if you're willing to be very patient, I could fill out the promotion and send the 5 cars and 2 promos after I get them in 2-3 months.  The catch would be that I would require payment up front if no trade were involved.

Let me know.  If no interest, then I guess my KMart's will just continue to sit on stock!
