When thinking of bidding for an antique or collectible, check the shipping costs before you bid. We just heard about an online auction that sold a large brass cash register to a bidder in Taiwan. When he learned that the shipping cost would be added to the bid and would double his expenses he didnt complete the sale. Shipping charges for large furniture and other heavy pieces, even expensive paintings and ceramics that must be crated. can be significant when calculating the cost of an item.
