I can send $500 cash to you via U.S. Postal Service in exchange for 1.44 BTC if you are willing to send first and to wait 5 to 7 days for First Class Mail (I'll pay for the $0.49 stamp).
If you want the cash faster, I can send you $500 cash via Priority Mail (2 to 3 day delivery with tracking number) in exchange for 1.46255 BTC.
If you want the cash really fast, I can send it Priority Express (overnight delivery) as soon as the post office opens in the morning in exchange for 1.50299 BTC. In that case you'll have the cash before noon Friday.
Sounds good but I don't want to take the risk that the money might get stolen or loss in transit. =/
Ok. I can send a U.S. Postal Money Order that you can cash at any U.S. Post office. The post office will replace it if it is lost, stolen, or damaged. We'd just have to increase the amount of bitcoins that you send me to compensate for the purchase cost of the money order(s). They cost $1.25 each.
