[quote name='Silence4520']I have a huge question, i have three games to trade in Portal 2, Infamous 2, Mortal kombat 9,
in Best buy
Portal2=20
infamous 2=24
mortal kombat=23
total=67 + 40%
preorder bounus= 25.6
Best Buy Final trade in Credit=89.6
by the trade-in Value on CaG for gamestop
P2=18
I2=25
MK=24
T=66+50%=99
so i'm wondering does it stack with the 10 %
and if it does is it 10% added first or 50% first?[/QUOTE]
The 10% stacks, but the value you get after one bonus doesn't then get increased by another bonus. You'll just get 60% extra, not 10% then 50% or vice versa.
