Donut help

The exp/money bonus that premium items give isn't working correctly at the moment I think so I wouldn't waste money on that. And you'll get mystery boxes for playing every 5 days and you could risk getting something lame like a tree.

I would say save the donuts to get something better. I have 120 donuts without ever buying them and I'm sure with seasonal updates there will be a few given for free.

Just my opinion.
