Unfortunately it doesn't work like that. Some people put Rangers above all else,there's another thread where someone 40k in debt would pay towards their season ticket anyway. The one about part refunds where you're not a real bear if you ask for a refund.
Some can afford it and would, some can't afford it and won't and some can't afford it and shouldn't. Bringing in that stupid loyalty scheme will make it worse as that will put more pressure on people.
There is too much uncertainty with peoples incomes at the moment for some to even consider this.
