If you have PayPal, in your wallet, you can get a Master Card Virtual key almost instantly. Once you have that set up and BEFORE you make the purchase, ensure you select to use the MC first for purchases AND ensure there is money on it. You can transfer money in using your bank account which takes a couple of days OR you can have someone send you money via PP and you add that to your MC instantly. The first time I used it, it was rejected and I got the email from RF saying they need to be white listed. I contacted PP and they told me there was insufficient funds. After a few more rejections and figuring out to make the MC first choice and adding money to it and then entering the wrong security code, I started the process of BitCoin which was going to take several more days. One last try with the correct numbers and wallaa it worked. Great stuff and happy with it.
