There are a few reasons why when you submit a promo code, it won't work.
- The promo code has expired. Promo codes are only valid for a certain amount of time, which could be hours, days, or weeks.
- The promo code was already entered. If you previously submitted the code, you won't be able to earn points for submitting it again.
- The promo code reached its claim limit. Sometimes a code will only be valid for a certain number of submissions, and when that limit is reached, the code will no longer be available.
- You misspelled the code. Check to make sure you are inputting it correctly. Codes are not case-sensitive.
