When you create an offer ad, you can limit the number of people who can view your offer by entering an amount in the Total offers available field. To provide an unlimited number of offers, you can leave this field blank.

If you want to limit the number of people who can view your offer, remember:

• For offer ads, if you use the Total offers available option, once the number of available offers is reached, delivery of the ad will be paused and no additional people will be able to save your offer.
• If you decide to use unique codes for your offers, the Total offers available can't be more than the number of unique codes that you uploaded.
