Do something about those VOUCHERS

I have 2700 vouchers,what to do with them,Please find some solution to it.

Save them for Diamond League.

use them to buy gems if you are free to play or to buy food if you pay to play

Gems and food are the best option.

You can also buy a worker.

7000 vouchers,that to at discounted rate,My saying is that get rid of this,in between so many updates and glitches,they have forgotten about it.
