price tracker??

I can not seem to find a price tracker for

Ones like camel camel camel is for just amazon

Don't know how well the trackers below work, but:

Shame there is no camel camel camel type site for Walmart that shows price history for a URL for Walmart product.

or for target, or for newegg (there was crazyegg but it went the way of the dodo)

Has anyone used I looks like a good site but doesn't have much price history.

It looks like a fairly new site but appears to be the camelcamelcamel for Walmart
