1901 Club monthly payments

Could you give me some idea when the monthly DD payments will commence for 1901 members. According to the agreement I signed the monthly DD commences on the 1st of the month prior to the first ticketed sporting event at the Stadium. If thats either the Sussex Cup game or the friendly against Spurs in July then it could be the 1st July but if its not until the KO on the 6th August then presumably the 1st August is the start date. Would help with budgeting if you could confirm which.

Thanks

First payment is due on 1st August.
