For vendors would it be safe to use shipnik.com. You can pay for priority mail postage with Bitcoin and you can add any return address to the label. It also would blend into the mail more then stamp packages.. right? For someone new to the markets this looks pretty safe for vendors to use. Or I'm I over looking something??
The one thought I had on it is it's pretty obvious what type of people would pay for shipping in BTC (vendors). If this site is working with LE it would be pretty clear what packages to give a closer look at. That is just my opinion though
