A majority of groceries and supermarkets throughout the country are only allowed to carry () drug products either at the selling areas or check-out counters, or both, because these are simply bought by shoppers who may have heard, seen, or read these products on radio, TV, or print advertisements, are prescribed by their family physicians and dentists, or are endorsed by friends, relatives and associates. OTC products at the selling areas are displayed in massive facings in gondolas and display racks while those at the check-out counters are made available through dispensers and are mostly in tablet formats
