Hello, while I know its has its faults, I've found that shipping cash via USPS can be fairly safe if done correctly. It is legal to send cash in the mail, and you can even insure cash if sent registered mail or possibly overnight express. I buy and sell precious metals for both Bitcoin and Cash, and when I accumulate Bitcoins, I need to convert them to USD to buy more metals to deal, and paypal/bank transfer doesn't cut it most of the time. If I want to go into a local shop and pick up some coins, I need cash.
So if you are interested in working something out, I'd be happy to use escrow, and leave me a response here or pm me.
I've got around 7.5 BTC currently to sell, in any increments you wish, I just ask that purchases be larger than $20, else its not really worth messing with.
