I had a prospective client contact me via my business email asking about pricing on 2 Bose 650's. I emailed him back with pricing and shipping to which he replied that he would call me with his CC number after he spoke to his bank to get his CC pre approved. I just started taking CC and am not sure that I like the sound of this. Not a great time to be out that kind of money if it is a scam. What protections might I have against CC fraud? I use PayPal CC capture.
