Does a promo code need to be unique?

Yes, you are not able to use a promo code for multiple types of promotions.

Is a promo code case-sensitive?

No, you can have any sort of case for your promotion codes. As a best practice we recommend always making your promo codes in UPPERCASE without spaces or special characters. Examples such as BOGO50 or SAVE10 are both good examples of promo codes.

Can a promo be applied to specific product(s)?

Yes, you have the ability to restrict promotions to specific products only. To do this create a new or edit an existing promotion and select one or more products under the Eligible Events section.
