The corporation also agreed to acquire the prescription files of 625 Rite Aid pharmacies across 15 states in areas that CVS serves, a spokeswoman said.

What isn't clear is whether the Bartell name that has been such a presence in the Seattle area will survive, with several experts warning that the ubiquitous brand could disappear.

Rite Aid plans to sell the majority of its pharmacies to rival drugstore chains. CVS Health is one of the largest buyers, snapping up prescription files from hundreds of stores and fully acquiring 64 brick-and-mortar locations.
