$10 off of every $20 spent coupon?

[graphical_force]

Hello, I'm trying to see if it is possible to have a coupon where it will give $10 off of every $20 spent so it is not really a half off type of thing.

Is this possible?

Thanks in advance!

This is not something built into Zen Cart ... you would have to re-write the code for Discount Coupon to handle a Discount Coupon like this ...

I am a developer but I am new to Zen cart. Could you point me in the right direction on where I can get info on how to tackle this issue?

Thanks.

Most likely the customization would be in the:
/includes/modules/order_total/ot_coupon.php

to adjust how the calculation is made ... but you will need to figure out how you want to identify these Discount Coupons with limits ...

Thanks,

Do I have to worry about the file be over written when an update is done? I do not want to get rid of the original way the coupon works I want to add another new functionality to it.

Yes you do there is not an override file for this so save a copy of the original on your computer and a copy of the changed file ...
