Use of Grocery Store Data

I am sure all of you have seen or used a grocery store card to receive discounts on purchases. These cards allow stores to link together purchases made over time to a single customer. I know there are many potential uses to this kind of data. On Friday I finally saw a use to this data that I agree with. Kroger sent my family in the mail personalized coupons. These coupons were for in all but one case items that we have bought in the past. We plan on actually using these coupons. I am not sure what the incentives are for Kroger, but I will be glad to use coupons for things my family was planning on purchasing anyways.

Well done Kroger.
