This morning I generated 5,000 unique promo codes for AppSumo to promote my Landing Page Services. I'm offering a 33% discount on my regularly low price. I wanted to change it to 50% off but it looks like the deal is locked-in and they didn't respond to my tech support request. If they do, I'll lower it to 50% since it's only 5,000 and would be an interesting experience. They say it will be 1 to 3 days for them to approve then it will launch.
I'm really curious to see how much business this generates. AppSumo boasts 1M page views monthly and since I signed up with them I must admit they do a good job of emailing everyone promotional information about the SaaS being sold on their website.
