Today's daily double deal at Ebates is for 5% cash back at Bluenile. Bluenile sells diamonds and other jewelry online. They have some very good prices for diamonds. If you're in the market for an engagement ring then buying today would be a good way to get an extra 5% back with the Ebates cash back rebate. Just make sure you don't spend too much on an engagement ring.
To get the 5% cash back you need to be signed up with Ebates. Then simply go to Ebates to get the referral to the Entertainment site before you do your shopping. I also get a referral bonus if you use my links to sign up with Ebates.
