Other companies offer credit card sales. That protects the consumer.
Not sure what you mean by customs My products come right in the mail. No broker needed. No Customs fee's. Even though Im self bonded for importing if I had to mess with brokers. I ordered an item on the dec 22 from China, as of today, it's landed in the USA, in California, and moving towards me.
Things change fast, as with almost all industries, Chinese are taking a bigger and bigger market share, selling direct into the USA.
Nothing personal, sounds like you run a good operation, although after googling your business, I see where other people have claimed you are a scammer:

That customer there, assuming he's telling the truth.. I believe nothing of what I read, could have protected himself if the transaction was via Credit Card.
