I don't know, but you can find it on DVC member.com. It's about $100 off a new AP, but I think the renewal discount was less, because the renewal price was less.
I just renewed our passes yesterday by phone with MS.
I always get a code to present at a Guest Relations Desk in order to get the new pass, never an actual ticket or voucher. We do this every time because our passes expire mid-August, we always have a trip mid-August, and Disney won't let you renew more than 30 days prior to expiration. So I never have enough time for anything to be mailed...the code works just fine anyway.
