Show HN: Traceur, my weekend project to auto-track shipments found in Gmail

Basically, Traceur requests access to a Gmail account via OAuth and scans hourly for any valid FedEx, UPS or USPS tracking numbers. If it finds some, it adds it to the database and periodically checks for status updates. I plan on charging $1.99 per month for this product as it seems very useful for general consumers (I started building this because I wanted it for myself) and also people who order a lot of things for their business. (Artists, repair, office managers, etc.) If you want to try it out, each account comes with a 7 day trial period. I have a couple 1 month free codes I'm willing to hand out for people who are willing to give me some constructive feedback.

Next features I'm working on are notifications (via Pushbullet) and then hacking out the mobile applications.
