Another bunch of "tokens", likely with standard formula - get 5k from BP, and the cheapest thing of any significance will be 30k. Get the rest 10 tokens per 1000 dubs...
Also, 4 weeks? Why not make it bi-weekly so people would be paying 6k dubs for a premium pass eight times a month?
In the end, no coal past the max level is the deal-breaker. Premium pass lost its value.
