The Father's Day coupon announcement is some forum bug, there is thread pinned to the top of the commons forum about it. Underneath the announcements. http://www.daz3d.com/forums/viewthread/2219/

There's a thread in the PC forum about that voucher, I think they've changed things so it now works on new releases. http://www.daz3d.com/forums/viewthread/1934/
