I find that purchasing or renting movies and tv episodes with Amazon is really nice - i don't have any late fees, and I don't have to brave poor driving conditions. I recently purchased episode 1 of Dr. Who season 7, which hasn't aired yet here in the states. It was a only a few dollars. I can wait for the whole season to air, but it was really fun to get to watch one episode before anyone else I know has seen it.
I spent about $5 today. I grabbed a coffee and oatmeal at a coffee stand. It was a treat for myself when I had been out and about town this morning.
