Just a reminder that Determine Your Discount is highly frustrating when you can only add 1 of an item to your cart. So shared storage, character slots, etc. can never achieve a level where you can use DYD.
Maybe that's the idea, but it's still disappointing. The "30% off allowed up to N times/account" solution from earlier this year was far nicer.
Alternately, you could think about some form of rebate program of purchases within a given period of time. (Though if that is buggy I make no guarantees about how badly your support team would get mobbed)
I agree with this. I was trying to buy more storage, character slots and shared cosmetic slots only to find out that I can only put 1 of each inside the slot... It would be nice if we could put more of these in the cart.
