Added Choice

An idea,you get five different mobile chess bundles,which is fine.For players that don`t want an annual or monthly payment.Why not give the option to buy a certain amount of moves and then they can use them as they see fit.If the moves are used up they can buy more if the need arise,then mobile players have an added choice.

I would like to know what mobile chess players think about this idea and if the majority agrees how to take it further.
