I haven't bought anything that exciting (yet)
We had a big cold spout for a few days so I bought a little ceramic heater to give a particularly troublesome room the extra blast of heat it needed to keep the actual heating in the house. It was about 40% off so it was also a good deal
I'm thinking about getting some more storage for my home PC, I usually find that deals on amazon aren't usually super amazing on many things but the storage prices aren't too bad. I'll probably impulse buy some stationary on sale in the next week or so though...
