What is the alternative? Is there an open source version that is community curated?

I set up a specific junk email address for this purpose and give to every retailer I shop with for their initial x% discount, and I receive coupon codes going forward.
From what I can tell, this is the best way to get discounts. Retailers are generous with people they know a lot about. The flip side is that you're going to be a target for their tricks. If you click on a link or add something to your cart, they are going to send you reminders and even more discounts to get you to buy that item.
Personally, I've been happy with this setup. I only see the promo spam when I want to. And my email becomes a personalized coupon code search engine that contains much better deals than you could get by using retailmenot or similar sites.
