CraigWatcher was born out of a desire to purchase an item on craigslist, but the problem was the item in question was very popular, and would often sell very quickly. Every other craigslist monitor required the user to install the software on his/her computer, and only recieve notifications on that computer.
With CraigWatcher, you can create a watch for a search phrase in a specific category, and we will email you within minutes of a match being posted to craigslist. If it is not so critical or you don't want so many emails, you can specify to be emailed a daily digest of results instead.
New users are allowed to have 2 active watches at a time. This maximum increases with the age of your user account.
