I wonder if there is a way to allow "upgrades" using WC?
I have a Digital Download product AAA that sells for $10
I will soon release product BBB which is actually a much improved and advanced version of AAA
The new price of BBB will be $12 but
I also want owners of AAA to be able to pay only the additional $2 to upgrade to BBB
I have searched high and low and can find no way to implement this.
Can anyone suggest anything please.
Thanks in advance.
