We are new to bitcoin talk but we are not a new company.

A group buy works differently to a pre-order. A group buy is effectively one large order placed by lots of smaller buyers in order to get a better price and ensure that a product is made available to those who would not normally have access. This order must be paid upfront. A better option for all parties is not using an escrow, but paying via credit card which offers better protection for consumers even after the products have been delivered. I do appreciate the offer though, anything that protects our community is a good thing, as long as you aren't the scammer of course
