Cash = no paper trail. Always a good thing.
I would MUCH rather risk losing $20-$40 hell even $200 rather than risk my info on someone's server somewhere.
The easiest way is to send cash to a respected site (Like nirvana) and have them sent to a trusted address that you will not grow at.
Hell,
I even like to use either 1) a fake name or 2) my name misspelled.
That way should anything happen, fake ignorance. Anyone can send cash and get something illegal sent to someone's house. No proof you actually did it. However, if you use credit card, paypal, etc. and something bad happens (i.e. you get caught) they KNOW it was you. A much easier prosecution if they chose to (I know, they probably wouldn't).
But why make it easy to prove it was you?
Just my $0.02,
