My first hobby turned startup project – http://www.deals411.com/ (All your group deal needs in one place)
About 2 years ago I came across groupon. Since then I had started buying a lot of daily deal coupons. I signed up to such services as yipit and onespout. With the help of those sites, I was buying coupons from many group deal sites. Last year (2011), I got fed up with the fact I wasn't sure where I bought some of my deals. As a developer, I thought to myself there must be a better way. So I started writing scripts to go to these different group sites, authenticate, keep my session and allow to download the different coupons that I had already purchased from these daily deal sites.
