ATTLEBORO — With hoopla befitting a Hollywood premiere, Market Basket opened in Bristol Place Shopping Center this morning, making it the chain’s 74th store.

The official opening of the Attleboro store, delayed since last March because of an ownership struggle among the Demoulas family, was highlighted by an appearance of celebrity CEO Arthur T. Demoulas as enthusiastic shoppers scooped up opening-day specials that included $2 boxes of cereal and a 99-cent cleanser.
