Jgregoryt:
What are these used for and how do I redeem them?
They have 3 basic uses:
1) use them as entry fee to coin games where you win - even more coins! (I guess you could say in a way you can use them to earn apparel boxes and balls during Showdowns since those are the prizes for those, and now you can win other stuff during this new Coin Chaos),
2) upgrading apparel attributes,
3) there are limited number of crappy clubs you can rent for a week (for an outrageous amount of return on the dollar)
