My sister lost my USB mini-b cord to my finepix A500 digital camera, is there anyway to buy a new one?

The website for fujifilm was completely useless, it didn't sell any USB cords, does like Best Buy or Wal*Mart sell them?

You can definitely get the cord at Best Buy, Staples or Circuit City.

you can buy it on the www.taobao.com.

In the mean time buy a card reader and use it. It will save your batteries in the camera too.
