If i have this right it will help cash flow a little bit.
When I renewed my season tickets I am sure the club stated that you would be refunded for all the games that you were unable to attend due to the restrictions so even though many will have paid up front the club will have to pay back for the matches missed.
So allowing members in reduces the number of refunds and also allows some match day spend on food, drink and programmes etc.
I would guess that this process will be more of a question than an automatic refund. So I expect the club to email me telling me that the board have propped up the club over the last 12months and I have a choice of a refund or can donate it.
If there are more than 4000 members then it will be interesting to see how they decide who can attend.
