I know the reward certificate for pre-owned can be stacked by using one of each at the same time: $25, $15 and $10. But I don't know about the reward certificate for new products, do they stack the same way such as a $50 and a $25 in one transaction?
Nvm, I just read the footnote that says "Two certificates of the same denomination can not be used in the same transaction, but you can use two different denominations." So the reward certificate for new product can be stacked the same way as the pre-owned certificate.
I haven't tried it yet but it sounds like Yes to me.
