Guilty luxury

I am cheap. I don’t think I go quite as far as being a tightwad, but I’m frugal. I buy generics at the supermarket and drugstore, and when I order from Amazon, I always choose the free shipping option, even though it sometimes drives me crazy waiting for the item to arrive. I don’t mind spending money on functionality, but I find it tough to spend extra for luxury. Today, however, I did something I found difficult: I paid the extra money for seat upgrades for our trip to the UK later this year.
