when you sign up, the corresponding info goes over to BRS, which they in turn register the group buy date (which is 7 days from the start date) and they enter in the members emails that are associated with that group buy. once the group buy starts, when you log into your BRS account, itll say "group buy member" at the top. at that point, youll see any and all discounts reflected at the item description screen. its pretty simple and straight forward. oh and you can order anytime within those 7 days.
