Is anyone using Shoptagr? Apparently it's a new site that tracks the items you are interested in and tells you when they go on sale. Putting Me Together mentioned it recently:

I've been wishing for something like this for Nordstrom instead of having to check my wishlist compulsively. I haven't signed up yet; thought I'd check if anyone else had experience with it yet.
