Another hotly debated topic. The tough part about international shipping is
the potential for fraud, cost of shipping, establishing acceptable payment
terms, and language barriers. It takes a bit of work initially and a little
experience to get used to these types of transactions, but the potential for
higher profits is tremendous.
If you want to dip your toe a bit before plunging in to the world-wide
market, eBay lets you select certain regions giving you some control over
your exposure on the various worldwide eBay sites. From the United States,
you might want to try just Canada for a while until you have a level of
comfort with International sales. Once you feel you've mastered Canadian
sales, expand to Europe or Australia.
When you decide to offer your goods to International Buyers, you'll want to
be sure to specify how you want to be paid. If you get a request from a
potential buyer asking if you'll accept payment type X, it's always a good
idea to check with your bank to make sure you aren't going to be hit with
any outrageous fees. As a general rule, it you are taking payments in U.S.
dollars and the payment instrument is drawn on an American bank, your bank
shouldn't be charging extra for these types of deposits. If they are, shop
around and find a bank that doesn't.
