Inadvertant Credit Card Payment...

If you have been reading I have rambled on about points rewards quite a bit lately. However, I came across something by accident. I purchased something on points recently and had to return it as I purchased the wrong size. Normally I assumed that the purchase would simply replace the points on my card, but apparently I was wrong. The purchase came off my credit card in cash. Therefore, $55 came off my credit card principal. Very exciting!
