I have been using them for just about 7 years now, always paid with CC, never had any issues w/ fraud or CC theft. Maybe im just lucky? Can't beat their immediate 5% off if you find a cheaper price anywhere (but amazon, they don't count amazon as legit competitor hence they don't honor their prices for watever reason, yes i know its crazy lol). The thing i hate is they ship at the rate of a snail at best! Takes them weeks to process the order, then more weeks to ship it, then a week or so to reach you. By the time its said & done, its like 5-8 weeks from purchase time to receive goods in hand !!!
Well, i wasnt so lucky with some RCs i used in the past. After making 2 purchases in the same day with 2 RCs (that i haven't used in the past), one week later i had a fraudulent transaction from a different state making a $2K purchase from a guitar store in Cali. WTF!
I use a couple of trusted RCs now, and no issues w/ fraud.
