There are seven campaign slots available per day. Promotions will generally be launched from 17:00 GMT onwards.
If a date is blanked out, that means the day is fully booked. You will have to choose the next available date.
Please be sure not to double book this type of campaign with another as there will be overlaps with our audience.
Be sensible in the time you leave between promotions. Give at least a week between repeat bookings.
