1. Buyer and seller both need to contact me and provide details of deal.
2. I will then send them a confirmation pm and both need to agree it.
3. Buyer need to make payment to me and include escrow fees (If he's paying escrow)
4. I will then send seller a payment confirmation pm. (or the seller checks the bitcoin escrow address using any block explorer website.)
5. Then Seller needs to provide item to buyer and pm me tracking/proof so I can check it and confirm delivery with buyer.
6. Upon buyers confirmation, I will release escrow.
The most important part is the shipping needs to have tracking and can be checked online. For your own protection, you may want insurance as well but that is on the seller.
Dabs, thanks for the info. Beside BTC, do you have other modes of payment?
Also, in the event the product shipped is not what is agreed on (I apologise for my ignorance) and I don't accept the delivery, what then? Like, it's a brick or something.
