Currently, Zencart excludes Gift Voucher purchases from the Discount calculated at checkout. Regardless of whether the Coupon has no restrictions or whether the coupon is specifically set up to allow the GV product code in "restrictions" it is still excluded. To clarify, I would like to offer a $100 Gift Voucher for $90. The coupon would only be allowed once per customer. Also GV proceeds could not be used to then purchase an additional GV or someone could easily game the system. I have looked in the Order Total module and have not found any place where the GV is specifically excluded from the calculation. Can someone point me in the right direction?? PS - I am not a developer so please excuse any misuse of terms.
