CVS: Paying You, With Extra Bucks, To Use Reusable Bags!!!

This is pretty neat. I have always used my reusable bags at Aldi but never at CVS; but I think that I might start because of this little green tag. You can purchase this little tag (located by the register for $0.99) and every forth time you have it scanned (because you are using your reusable bags) you will earn one ECB (Extra Care Buck).
I know that this week if you buy 2 of these CVS will give one ECB; or you can go to Recyclebank.com (sign in or sign up here --they give you 100 points just for signing up) spend 25 points for a B1G1 of these CVS tags.
