I installed Credit coupons en Gift Vouchers: CCVG (trad) v 1.2 http://www.oscommerce.com/community/contributions,4135
Entering a couponcode at checkout leaves a discount (modules/totalpayment).
The maker of the contrib. delivered a fix for Paypal IPN to charge the ordertotal minus discount. Works OK; but:
Previously I installed successfully the dutch iDEAL interface v 1.2.1. for electronic paymens.(http://www.oscommerce.com/community/contributions,3759)
The ideal payment (idealm) however does not take over the discount in a net total amount. What/where to change the idealm contrib.?
