Discount Coupons


Recommended Posts



I am using discount coupons on my store, however, when the discount coupon is applied, it uses the pre-tax price of the product/shipping in its calculation.

So £2.95 shipping, with 100% discount only applied the pre-tax price of £2.51 discount.


What is going on? How do i correct it?

you need to change the sort order in Order Total Modules.

Please read this line: Do you want to find all the answers to your questions? click here. As for contribution database it's located here!

8 people out of 10 don't bother to read installation manuals. I can recommend: if you can't read the installation manual, don't bother to install any contribution yourself.

Before installing contribution or editing/updating/deleting any files, do the full backup, it will save to you & everyone here on the forum time to fix your issues.

Any issues with oscommerce, I am here to help you.

in fact i think I know the problem....

I am using table rate shipping, and the prices in there are pre-tax, but because they are asigned to a tax class, the tax is added after.

So, the module is taking the literal price that is in the tables without adding tax to it, but OSC is adding tax because of the tax class?


How can I resolve this?

I have taken a look at this a bit (with my basic/medium knowledge of code) but I cant seem to work out if its an error from the installation of the module or OSC as a whole....


Can someone please help me get to the bottom of this...? I have a lot of customers eager to get their free shipping! lol!
