Answer: Frequency discount
Step-by-step explanation:
Frequency discounts are the type of discount usually offered by publications such as newspapers or magazines. Normally to earn frequency discount has to do with how often advertisment is run by the advertiser. It doesn't have to do with how large the advertisment is but how frequently it's done.
For example, someone who runs an advertisement twice a week will be given a better frequency discount than some who runs an advertisement for just once a month.
