It compared prices of branded products with a supermarket's own-label equivalents. However, own-label equivalents have been available for many years (in local pharmacies, too), and the potential big savings implied already exist.
The savings will come if branded products drop in price; the difference between branded and own-label goods has nothing to do with the RPM issue. If RPM does go, it will undoubtedly mean savings on branded goods - but only coppers. The implications for those who rely on pharmacy services could be far more costly.
