Thanks for that quick update, tested and is behaving ok. I do note that the email receipt may not be ideal, as the ‘subtotal’ line shows a negative amount if the coupon value is higher than the purchase amount:

Product Name: Webinar for £10
Quantity: 1
Item Price: £10.00
Coupon “test12”: -£12.00
Subtotal: -£2.00
——————————–
Total Amount: £0.00

I think it would be better for the subtotal to appear as zero, and arguably the coupon amount should only show the amount that’s been redeemed, i.e. the product price, however these aren’t deal-breakers. The danger here is that the customer might expect a refund of £2 looking at this receipt.

I’ve run some tests as suggested but I’m getting inconsistent results. When the coupon value meets or exceeds the product price it’s working as expected, but it’s also sporadically reducing the price to zero when the coupon price is lower than the item, for example product at £10 applying £9 coupon gave it for free, and also product price £55 with £33 coupon also gave for free.

So whilst I can’t be specific about why this is failing, this doesn’t appear to be a good build.

FWIW, and I obviously don’t know my way around the code, I modified the Load_coupon method for the Item class to check the coupon value and if >= product price then transform it into a 100% off, which is then handled properly by the rest of the plugin code.

if(intval($this->coupon[‘discount’])>=$this->get_price() &&
$this->coupon[‘discount_type’]===’fixed’){
// transform this to a 100%
$this->coupon[‘discount’]=100;
$this->coupon[‘discount_type’]=’perc’;
}

Hi, the product price is £33, and the coupon is ‘fixed amount’ of £33. I did also experiment with higher value coupons, and the total price went negative(!)

… and then payment processing reports ‘Error occurred: This value must be greater than or equal to 1’ – so it doesn’t work anyway.
