Why are amazon prices always changing up/down

[chaparral]

Does anyone know why the prices on so many items on amazon change all the time ? sometimes it can even be every couple of days

Am sure many people on here have also used an amazon price tracker and noticed the exact same thing..

Use that, massive help.

I used to use that camelcamelcamel website

But i found this Keepa app is far better as it shows the price history striaght away on the actual amazon web pages of the items you're looking at
