We have a standard practice to give our Super Admins a coupon that enables 100% discount for testing orders.
This way, we're not actually using cards, payments, etc.

When I setup a 100% discount coupon and try to use it, my experience is varied:

1.) On the basket page (domain.com/Checkout/Basket), I get a perfect 100% discount. In my example, I am buying a single product that sells for $28.01 and my coupon (100% ) is good for -$28.01.
2.) When I move into the order processing (/checkout/EditBillAddress) the summary shows total fee of $28.02 (NOTE THAT NEW AMOUNT), minus a coupon of $28.01 for a balance due: a $0.01 'charge' in the payment due.
3.) If I add more SKUs to my order, the balance due is a a SUM of the number of products. So TWO SKUs now has a balance due of $0.02; Three SKUs gives me a balance due of $0.03; Four gives $0.04, etc.)

It's almost as though the order Summary is calculating the 100% discount, but then is adding in an amount that is equal to the # of SKUs.

It's important to note too that the QTY per SKU does not affect this. If I have 5 QTY in one SKU, the fee increases only $0.01. If I have 5 SKUs it increases $0.05.

Hi Mike --

Running AC 9 RC3, for sure.

Yes, I did realize that the Basket doesn't allow you to add a coupon. I had added on a later screen (the payment screen) and then went back to add more product. That's when I ended up on the basket screen, showing the coupon at 100%.

Could the back-and-forth have created this issue?

Thanks,
Steve

Hi Steve,

I still want to figure it out, but when we are testing we just assign the call me payment method to the admin groups. So you still have a valid order total and a valid unprocessed payment.

Hi Katie --
Sorry for my late response... it's been rather chaotic here lately and I'm getting back on this.

1.) Created as an "Order Coupon"
2.) It's a 100% Order Coupon -- There ought not be any tax with a 100% discount, right? I had not stopped tax calculations in the store, though.
3.) Shipping hadn't yet been calculated.
4.) No there was nothing unusual about the product that I can recall.... we have several thousand skus: I'll see if I can replicate now.


Thanks!
Steve

Hi Mike,
I cannot duplicate it now. Not sure why.
I'll keep and eye on this and if it comes up again, I'll bring it back to you.

Thanks,
Steve
