Those rewards sound good! Here are a few ideas...
A day at the spa (nails, facial, massage?, whatever you enjoy)
A new dress or outfit that you might not normally spend the money on
New make-up
Go for a special outing (museum, movie, etc)
Thats all I have for now. I would love to hear other ideas you come up with and I will let you know if I think of anymore. Good luck!!!
