New grocery store to open Wednesday A new Price Chopper store is slated to open at 8 a.m. Wednesday, July 16, on the east side of Wyandotte Plaza at 7600 State Ave. At 68,000 square feet, the new store will be larger than the existing one on the west side of Wyandotte Plaza. The space from the older Price Chopper building at the center will be the site of a new Marshalls store and PetSmart next spring. Red Legacy was in charge of the Wyandotte Plaza redevelopment project.
