Limited number of vouchers per hour. They are replenished every hour on top of the hour. Max 2 vouchers per FB account. Voucher value up to $7.50.
Best chance to get a voucher is using the app 30 seconds prior to the top of an hour. Keep sending coded messages until you get a picture of letters for bot prevention (which would lead to an unique claim code) or a minute or two after (by then the vouchers are gone for the hour).
