I stopped buying everything a almost a year ago although I had the donuts to do so. Last Christmas I bought the currency needed for the wheel and I still regret it.
I believe that whoever buys the currency of the event ends up with useless turns. It's like they have decided that those who pay for eggs they will have to either pay again or be patiened by collecting them themselves to get all the prizes. I really would like to dive to the files of the past few events and see for myself but :evil: the new way EA is using now to make them invisible..
