I saw a message today that the CS coupons were supposed to be retiring tomorrow, so I wanted to use mine. There's no window for putting in the code on the cart page, though.

They already disabled them it looks like. Luckily they're not disabled permanently, just for the duration of the sale, when normally they would have been from the start.

Ah, so it's just for the sale? I thought they would be gone forever so I wanted to use mine. Thanks.
