CVS scanning tags on reusable bags for ECBS!

Happyhousewife reported that her cvs manager said starting in October, you will be able to buy a tag to put on your reuseable shopping bags and every time you shop they'll scan the tag (once a day) and after 4 scans you get $1 ECB. I'm not sure on the details but it sounds like this was ongoing. I'm sure my fav cashier at CVS will think this is FABULOUS roflol!
