Hi there,
We recently installed the DISCOUNT COUPONS feature on our website. We've got it set for a 20% discount.
The order total comes to $38.85. Twenty percent is $7.77, bringing the subtotal to $31.08.
The customer's invoice looks like this:
Sub-Total: $31.08 <----the discount has already been applied
Discount Coupon applied: -$7.77 <---Another 20% discount
Table Rate (freight): $8.95 <--- add in the freight
Total: $32.26 <----- now, if you do the math, you can see it's deducting the coupon twice! :'(
Here's what I found:
In the admin section of the website, in the ORDER TOTAL MODULE, we had the following set to false:
Display subtotal with applied discount?
true - the order subtotal will be displayed with the discount applied
false - the order subtotal will be displayed without the discount applied
But the *false* setting doesn't work that way! When set to false, the subtotal IS DISPLAYED WITH THE DISCOUNT APPLIED!!
By setting it to TRUE, the problem was fixed.
So the $38.85 invoice now looks like this:
Discount Coupon applied: -$7.77
Sub-Total: $31.08
Table Rate (freight): $8.95
Total: $40.03
Anyway, by the time I had this all typed-out, I had answered my own question, and thought I would share my findings.
Best,
Sunshine
