Discount Sites in DC

Have you heard of all the discount/coupon sites in DC...  I am sure there are more but here are a few I like:

1. Groupon
2. LivingSocial
3. BuyWithMe
4. Capitol Deal
5. What's the Deal
6. Rue La La

Let me know what sites you follow so I can get on the bandwagon!

There are some others that are not exactly DC sites which are great. Groupon and LivingSocial apply to most major cities in the US.

Happy shopping!
