Couldn't find this info at the passport site and finally got in touch with someone about it. The msn passport promotion officially ends December 19. im sure that is subject to change at any time. also individual merchants can back out at any time or refuse to accept the passport discount. i dont see why any company would back out unless it's a hassle. i asked and msn foots the 20% off, it doesnt come out of the etailers pockets. this is sort of in relation to casiotech's post about mercata, i dont know if it will be pulled friday, but mercata can do it without any warning.
