On this week's Modern Retail Podcast, senior reporter Melissa Daniels is joined by executive editor Anna Hensel. First, they discuss Affirm's new rollout with Apple Pay to provide its buy-now, pay-later services in-store. Then they unpack the trend of paper coupons making a comeback in some retail environments, with Kroger announcing it has been bringing back paper coupons to help appeal to value-minded shoppers or those who aren't comfortable with more digital savings programs.
