Everything on that link was either a birthday present for someone else or a replacement ignition coil I needed once.
Actually, I did buy an adjustable sit/stand desk for myself on 12/29 but that was an in-store purchase so yes, I did make a luxury purchase for myself this year. I think I bought a XBONE game this year too. Maybe it was just DLC.
Things I'm waiting to buy are PC parts for first ever build (waiting to see what CES reveals) and I definitely need to buy some clothes. I haven't been clothes shopping for a few years.
