Cex price tracker

Hi, everyone I am just wondering if there is anything that can track price changes on Cex?

I was searching for a laptop last night, went through loads of items which I bookmarked etc and thought I'd take a proper look today but I woke up this morning to see all the prices had changed!

I don't remember exactly which have risen in price and which have dropped, I'm just wondering if there is a way to find this out?
