Thank you for the question.
Unfortunately our business model doesn't support escrow services, or any other external payment methods, due to the contract made with our suppliers (at least in the context of the current mass discount).
If you're concerned about the order transparency, you can still choose the well-established and track able credit card or bank transfer payment instead of bitcoin.
By the way, at the given address, if you look into it there is a shopping center, in which addition to our office there are more business, storerooms and plenty of large and small shops can be found. And yes, there are cafes and restaurants too, and they are pretty good actually.
