- Insufficient minimum spend on qualifying items in cart
- Discount was requested for items that are not qualified for discount (e.g. discount code for dining chair was used when only a dining table is in the cart)
- "Apply Coupon" button was not clicked
- Discount code has expired
- Discount promotion has ended
