This morning? [ame="http://www.amazon.com/gp/product/B000PWGZOI/"]This chair[/ame]. I'm pretty heavy and I have a tendency to shift positions a lot (from crossing legs to leaning forward to reclining to just plain slouching), so I'm hard on chairs. I'm dropping a lot of money on building a computer at the moment and am thus not ready to drop $500-$1000 or even more on a Herman Miller, Steelcase, or Humanscale with a 12-15 year warranty, so I grabbed a chair that gets "bang for your buck" awards at $415 while it was on sale for $172.05 after tax. Also I can remove the arms to make room for crossed legs.
Yesterday: I bought copies of
Undertale for a couple of friends (on top of a third one back on the 15th). Amazing game, low price ($10 normally, $8 on sale). Perfect digital stocking stuffer.
The day before yesterday: a
650-watt EVGA GQ computer power supply for the computer I'm planning on building. It's new enough that
customer reviews aren't in yet, but the experts who actually took electrician's testing tools to the thing and disassembled it to find out the quality of the components gave it rave reviews. A good mid-wattage-range power supply can easily run $100 or so, and I scored it at a grand total of $61.50.
Back on the 16th: a
250GB Samsung solid-state drive on sale for eighty bucks and free shipping, also for the computer I'm planning on building. It's basically a hard drive with no mechanical parts that is insanely fast and reliable as a result: we're talking stuff like booting to desktop in five seconds, a mean time before failure measured in millions of hours, and an annualised failure rate of like half a percent, at least for this brand and series (Samsung is one of the leaders in the field).
