Fixed Price Coupons

[bsmither]

Would someone who has mastered the creation of fixed-price coupons, and they seem to work for you, please participate in this experiment:

 

* You should have a product that costs 50.00

* Create a 5.00 coupon with Allowed Uses of 2

* Assign this coupon to that product.

 

As a customer, place 12 of these items in your cart and checkout.

 

During checkout, enter this coupon's code.

 

You should see a 10.00 discount having been applied.

 

Please reply if you get something other than the 10.00 discount.

• I have a $8.33 total discount reflected on the checkout page.  
• The unit price on the checkout page changed from $50.00 to $41.67 ($8.33 per item...)  
• The total price changed to $500.00 (from $600.00).  
• The subtotal ($500) plus shipping (flat at $7.95) creates a grand total of $507.95 (the original price less 8.33 discount on 12 items plus shipping...)

 

I have upgraded to 5.2.1

 

oops..  this is a mess.

 

I felt as if the coupons were working, when applied as a percentage or as a fixed price for all items.  Obviously, this isn't working.

when I unapplied to the individual product, the coupon worked as follows:

 

1 total discount reflected: $5.00, product price is still $50.00

2 total price is 600 (correct) plus shipping of 7.95 (correct) less 5 (discount) for a total of 602.95.

 

so the coupon worked when not applied to a specific product.

Thank you for your research.

 

Are you comfortable with making edits to the CubeCart files?

[fairview]

sure - do you have a solution?

[bsmither]

In the file /class/cart.class.php, near line 1152, find:

private function _applyProductDiscount(&$price, $product_id, $quantity = 1) {

In two places, about 20 and 30 lines down, find:

$discount    = (($price / $quantity) < $data['value']) ? ($price / $quantity) * $available : $data['value'] * $available;

On a newline after each of those lines, add this:

$discount = $discount / $quantity;

Again, thank you for your willingness to experiment.
