2. Input error - check if there are any extra spaces at the beginning or end of the line, or if there was a typo.
3. The code has already been activated - rewards for the combination can only be received once per account.
4. Limit reached - This means the coupon was limited in number of uses, and the fastest users were able to receive prizes.
