while not directly PD14 related, I might need some assistance here. Would like to upgrade (just because I am an upgrade freak :

While CL tech support merged my accounts, I somehow can't get them to switch me to my confirmed Platinum membership. There's a special Black friday discount, but I would like to know, if the Platinum membership has bigger discounts than the Silver one?
The offer runs out in 2 days, so any help is appreciated :

Thanks,
Petr
