If this is the same cheat I used to use, they closed the loophole that allowed you to do it an update or two ago...used to be you could save the game, use a coupon, and then if you didn't get what you wanted, you could just reload the saved game, the coupon would be restored, and you could just keep trying over and over again without saving the game again until you got what you wanted. But a few updates ago, they got rid of the manual save and went to an auto save, so it eliminated your ability to do this.
If the Club Rick cheat was something other than that method, then I'd be interested in hearing what it is, too...
You're a lonely, insignificant speck on a has-been planet orbited by a cold, indifferent sun!
