Goodwills are weird depending on who is running each location. Some have pretty straight pricing (small electronics $5, DVDs $1, etc) and then some try to price everything and are almost always way off. I also found a NIB Logitech G602 for $10 that I now use daily at work and I've also seen the other end of the spectrum where they were asking $200 for an Xbox 360 (in 2017!).
