fraudulent charges This happened to me before when purchasing items -- not upholstery related -- online.
Not sure which online suppliers you buy from, but my advice would be to stick with big, well-known online suppliers and retailers. Buying items from small, unknown websites (like I did) is a recipe for disaster. Once they have your credit card information, you're at their mercy.
Hope you cancelled your card and cleared up the issue right away. Best of luck!
