Online reward systems or reward systems of any kind. Grocery chain around me stopped sending out hard copies of printed coupons now you have to go to your online account which I don't have and manually select e-coupons before going to store. Than when checking out have to bring coupons up on your phone that I despise using and let the check out lady scan them from your phone so I've been told. I have rarely frequented store since this was implemented a few months ago.
