The price of the same bag at Kasumi or Hanamasa is more than 250 yen. Many other bargains, especially with snack food, which can be bought at virtually half the price of the same snack in a Seven-Eleven. Watch out for the best-before date though as they have been known to sell off nearly-expired items. No fresh produce or meats. Household & cleaning goods are most reasonable here too. The 2nd floor is an antiques shop.
