Deal Tracker App?

[JPDVM2014]

I just recently switched to WP7 from webOS. There is an app called Dealert that kept track of several deal sites and alerted you if it found any items that you specify in a tracking list. Are there any apps like that for WP7? I saw the app called Deal Tracker, but it doesn't seem like it has alerts. There is also a-z tracker, but it doesn't have many sites. Are there any others? Thanks.
