Welcia Susono Sano Shop

Last year it was an ordinary supermarket, but it was changed to Wurushia. I know only the price of frozen Gyoza for local Ajinomoto 's Ajinomoto and Maruha Nichiro' s frozen Gosho yakisoba, but the price was the same but the gyoza is different from the local 188 yen, here 215 yen (tax not included). I thought that it was the same price everywhere, but I felt that it seems to change with the price of competing stores in the neighborhood.
