Well, he does prefer a check believe it or not. I tried to use a debit card my first time, and I believe he said he could but he would have to "start up another machine over there". I sent him a check, and have ever since
I just bought a couple of chips from Red Armstrong a couple of weeks ago and had no problem using a credit card over the phone. He was also more than willing out help with other questions I had concerning rebuilding my motor. Very nice guy and I highly recommend doing business with him! Just my 2 cents!
