Okay, it's not really a deal, but adding the Invisible Hand add-on to your Firefox browser lets you search for available prices for items on the web. Available prices appear in a discreet notification bar at the top of your browser window.
I might be miles behind the times here, but I've just tried it and it works really well.
Doesn't mean you don't have to swing past HUKDeals though!
Hope someone finds it useful.
