The figure increases to 42% if the convenience store could include a proper pharmacy in it, with pharmacists working in it. Tom Fender, development director for TWC, said: “There is far greater competition for ‘top-up’ shopping today than there was 20 years ago. A huge percentage of visits to supermarkets are ‘top-up’ trips, as well as discounters taking a chunk out of c-stores’ top-up market. “Therefore, c-store operators have had to go fishing in ponds other than the ones they are used to. Almost half of 7-11 stores in Japan have a pharmacy within it.
