I am stumped on older camera prices?

I bought my daughter about 1 1/2 yrs ago the Fuji FinePix S5200 at a very good price.I don’t quite recall, something like $237-..buying same camera today say at Amazon.com
refurbished is $199.50 and New is $497- Does this make sense for an older camera?
So why is the price this way?
And $469.99 for one of my two p&s Sony DSC-H2 Anyone paying these prices?

It makes no sense. Maybe a newer camera would be a better investment. … at $497 you could have a real DSLR w/ 18-55mm interchangeable lens for under $470 and spend the little extra on more memory cards.

Thermal camera, FLIR infrared night vision
