Thanks to reader Steve for the heads up on this new offer from Ebates that DoC wrote about:
You can earn cash back and convert it to MR points. You can then cash out the MR points for 1.25 cents per point. The most recent 14% cashback from Dell and Saks would be the same as 17.5% cashback if converted to cash this way. This is for new accounts only, and had to use incognito mode to sign up for a new account at this public link.
I will be using this instead of my old cash account in order to take advantage of the 25% boost. Thanks Steve!
