A good number of digital coupons are manufacturer coupons. (I work in this space)

Kroger is usually pretty good about adding shelf tags that highlight the digital coupon.

I much prefer digital coupons to paper coupons that I always seem to forget. But I understand that there is a significant portion of the population who prefer paper coupons instead.

As for the topic of the post, I absolutely think regulators need to step in block the Kroger / Albertsons merger. We need more competition, not less.
