Hi
Not to be trying to revive a topic, but I've been searching on Google for a solution to this problem also and haven't found one - only this post contains the problem that I'm experiencing and I'm hoping someone will be able to find a resolution.
I'm currently running osCommerce Bootstrap 3 in 2.3.4 Responsive Master

I am currently trying to look for a working discount code and gift voucher model, but haven't found one (2.3.3.4 was the closest I found but it hasn't been formatted for BS codes yet - I'm not advanced enough to work out every difference required)
So in the mean time, I'm using Discount Codes 4.2.1 BS

I'm using PayPal to process my transactions - at first, I was using PayPal Express - but for some odd reason, it would never include the shipping. Going into my PayPal account, I've set a profile for shipping, still it charges for the total cost of items. I tried ticking that override profile issue, same thing. I read somewhere to click on Clear Settings and leave it all blank, same issue.
So I gave up on it and tried PayPal Standard.
Everything works fine, except when the discount is somehow greater than the total cost of items. Of course, realistically, this probably won't happen for any order, but whilst I was testing the module and codes, and to make sure PayPal was receiving transactions, that's when I encountered the problem below.
Again, this probably won't affect me, but I still would like to resolve this problem as a precaution, just in case.
Anyone ever found a solution to this problem yet?
