When my MIL died, my FIL (who is notoriously bad with money) had no way to pay for the funeral. I had just gotten my Disney Visa, and back then they had a lot of 12 months 0% interest on purchases. He called us to ask for the money for the funeral, I wasn't so interest in paying $9,000.00 with no time frame for repayment--but I also did not think it was right to stick it to the funeral home, they did their job.
So I called the funeral home to ask if I could put it on a credit card, the said no problem. I called my FIL and told him I didn't have the money, but that I could put it on my credit card that had 6 months free interest (I figured 6 months for him to not pay, and 6 months for me to drive him crazy until he paid). At the time I was not thinking disney points, but it was a nice gift to get the 90 disney dollars.
For the record, even though he did get $42K in insurance money, a month after my MIL died, it did take him the full 6 months to pay me back. I was glad I gave myself the the 6 month nagging cushion.
Now I use the Disney card for everything, my town even takes it fee free for my water/sewer bill--in an odd way I am flushing myself to Disney.
