I like to buy digital services which are being quoted cheaper than market prices. Once I have bought VPS and for bitcointalk members they have offered heavy discounts. More interestingly they accepted litecoin/dogecoin payments too.
I am really looking for something which are being sold with discounts as I am not limiting myself not to buy anything here. But I always prefer to deal through escrow only.
That is the biggest advantage you have when buying over here, instead of some markets that are available on regular internet that do not use bitcoin as a main payment method, but mostly paypal, bank transfer system or any other services similiar to paypal.
You might get a really great price over here for some digital goods, that is why I never visit such a websites first. If im looking for something that I can order and obtain only through the internet, then I dont even care about such a shops where I will pay like 30% more than when using bitcoin!
But to be honest, I dont see the point of buying anything that has to be ordered through mail with bitcoin, I wont be anonymous in that case right?
