Yahoo! Shopping Auctions Also U.S. based, but have country specific site as does eBay.
Unfortunately some retailers and individuals are auctioning off kits that are currently available in hopes of striking gold off of uninformed individuals who may think the kit is out of production. I saw a $4US Tamiya kit go for $41US because the seller implied the kit was out of production. In another case the seller said that the Tamiya "moulds were destroyed" and the kit went for $460US. Only to reissued a few months later for $90US.
Do yourself a favour and do your homework before bidding on a kit. Contact your hobby shop, mail order house or the manufacturer to find out whether or not a kit you want is still available at retail prices.
As they say, buyer beware. Be an informed bidder!
For example, if you live in Ontario, Canada and order from the U.S., a $50US item will cost: 50.00 x 1.48exchange = 74.00 + 5.18GST + 5.92PST + $5.00 Customs service charge for a total of $90.00Cdn. And that is without shipping/handling factored in!

People often wonder how safe it is to deal with companies or individuals in other countries.
There is a Corruption Perception Index compiled every year by Transparency International that uses surveys to rank countries.
Now you'll know why a company might be reluctant or refuse to do business with you. And I imagine these numbers could also indicate what to expect from doing business with a company or individual in the respective countries.
