Make secure, convenient payments for any Happy or Sad bucks or Sergeant fines.  You will get an emailed credit card receipt.   What you pay is up to you, in fact all fines and happy sad bucks are purely voluntary. 

You can pay almost any amount - for instance if you want to pay $40 hit the "$20" box and enter "2" rather than "1".     If you want to pay $23, hit the "$20" box and the "$3".  

Note the credit card fees to the club are 25 cents per transactions, plus a per cent similar to what all businesses pay when you use your credit card.  You may consider combining a few happy bucks or prepaying for the future, using the 4 Way Test.
