Im adding a coupon, but im confused about how to apply a simple discount.
I want to add a 10% discount to the entire order.
I choose Discount by a percentage based on this price from the Discount Type mrnu.
For Coupon Details I enter simply '10' assuming this would discount the price 10%.
Testing it out, I apply the code but nothing was discounted. Not even a mention of the code being used. I know it was used, because if I enter it again I get an error claiming its in use.
Im obviously not doing this right - how do I generate a 10% discount?
