We received an order this morning that had a 10% discount on the subtotal. When looking to see what promo code was used, nothing was in the field, other than a comma (,) to indicate something was in the text box

I created a test order, and before entering any shipping information, added a space in the coupon code box and applied it. The result was a 10% discount from the subtotal.

I reviewed every order total coupon code we have set up through our offers, and everything that offers a 10% discount requires a specified code to be entered.

I even tried to create an offer that did not reduce the order total (and even reverse it) where the required coupon code was just a space. This did not resolve the issue.

Please look into this as soon as possible. I'm also curious if this is happening for other stores.
