Specific product online deal alert service?

So, I’m in the market for a Blu-Ray player to go with my fancy new TV. I’m not going to buy retail like a sucker and want to try to scoop one through Groupon, Gilt, Woot, etc. However, I’m also rather lazy regarding this, and I don’t want to have to go through each sites’ daily offerings. The deal aggregator sites I’ve found are pretty much just large lists of everything on sale. I’m looking for something like Google Alerts for news - but for shopping. I want an email if, and only if, a Blu-Ray player goes on sale.

Does something like this exist?

Not quite what you want, but you can sign up for an email alert at Slickdeals.net if a Blu-Ray player is posted by someone as being on sale someplace for a better-than-usual price.

CamelCamelCamel has a price-tracker for Amazon, Best Buy, and Newegg. It will also show you historical price charts. This would work if you knew exactly what model you wanted (and if one of those sites has the best deal).
