I was able to get a 50% coupon on everything I purchased today at Goodwill.
I got some cool stuff, one of them was a projector for $20, looks new two.
But the big disappointment was some monitors I got. I found three monitors, two of them 1080P (moving most of my monitors to 1080P), the last one was really a 720P TV.
One of the 1080P monitors, I nice looking Dell kept shutting off after about 10 to 30 seconds of run time. The 720P smelled like it was gonna catch on fire.
But at least got one of them to run, also was able to get a refund on the other two.
Moral of the story, test your electronic devices ASAP when buying used.
