Why not do a direct bank transfer, it is the safest method, or sign up to Paypal, it is very easy also AND you get some protection too. I use Paypal all the time. If the recipient also has Paypal, it is the easiest method to use, and is more secure than using a credit card. For a start, once you are sign up, you only have to log in and don't have to enter your details all the time. It really cannot be simpler.
I just placed an order with ADM using Paypal and I didn't even have to input my address, as Paypal does it all for me.
It doesn't get any easier than that, but then, someone told me a long time ago, "give a lazy man a job and he will find the easy way to do it......every time."
I always do!
