It looks like Puregold will be opening a store in Taguig soon. It's located along M. Almeda Street, near the Taguig City Hall. An approximate location has been posted at wikimapia, for those interested. It's not clear yet, however, what type of grocery will be opened - Puregold Jr., Puregold Extra or Puregold Price Club.
I pointed out the lack of groceries in Taguig in an earlier post. So this is actually welcome news for Taguig residents like me.
