O.K. I'm going to TRY to reform why viewpoint in the future, perhaps with the exception of international sales. I feel the U.S. is populated enough to create good competition on any given item.
Additionally, with international sales you're introducing additional risk: a third party in the transaction, namely customs brokers w/ concomitant customs fees, longer shipping times, and "foreign credit cards"- I don't know exactly what risk the latter entails, but I know that many of the heavy volume professional photo dealers won't accept the foreign transactions/cards, so they must be NOT accepting them for a reason. Why wait to get burned to find out why?
PS, I'm outta bed Dan, and may even go into a Dark Room :-)
