When you register, you'll be given a list of search options. Once you have selected the options you are interested in, we will sign you up for our hourly inventory check. Every hour after you register, we will compare your search options to inventory that has been entered recently. If we find that we have inventory matching your criteria, we will send you an email letting you know that there are new items listed on our site matching your search options. We'll never send you the same inventory more than once, so you'll only receive an email for the latest inventory. And you're able to easily unsubscribe yourself from our service at any time.
