I agree. These are free points that don't cost anything and you can exchange them for Gift Cards or Miles. I received 5 emails today. 3 were worth 5 points so I clicked on them. The other 2 weren't, but 1 of the 2 informed me that Overstock.com was offering free shipping, something I've been waiting on.

While I didn't click on the link in the email, it was useful information and I will be ordering stuff from Overstock tonight due to the free shipping.
