You can often contact the seller and ask him to allow you to bid. Sellers often block foreign bidders because of shipping hassles. I just got an email from Ebay telling me that they have anew program to make international shipping easier, so that might be worth researching too. If you tell the seller that you are willing to pay actual shipping charges, the seller may reconsider.
