If you extend your offers, you’ll be billed $2 to extend whatever Offers are extendable that month on the first of the following month. It's $2 no matter how many Offers you have in the app. Sometimes, no Offers you have are extendable, in that case, you would not be able to extend your Offers.
Monthly members will see those additional charges alongside their regular membership subscription receipt.
Annual members will get a single invoice that contains their Offers extension on the first of the month.
