Hey guys, we have a tiered upgrades system, and I was looking for a way to discount higher upgrades if you purchase a lower one.
Example:
I buy Gold Donor for 20$, and want to upgrade to Diamond Donor (Normally $30), but since I payed $20 already, it's only a $10 upgrade.
I haven't figured out a good way to do this. =/ Any ideas?
