So if albertsons gets bought will pavilions vons safeway and the other companies they own go with them
Maybe. Kroger is aiming for market share (as compared to total U.S. grocery sales volumes) so as to compete with Walmart in the prices that they pay to largest suppliers (greater volume usually equals lower prices). But they know that a big part of the merger game is competition. In the past, it has been common that Kroger will spin off entire subsidiaries in order to deal with complaints (local and regional) about anti-competitive forces of the merger. When Kroger has spun off a handful of local stores of a particular subsidiary chain, they sometimes get them back in another unrelated store swap later on (but operating under a different name). Who knows how many stores and chains will get spun off. Additionally, Kroger is particularly focused on picking up regional market share in Florida.
Other chains owned by Albertsons are: Jewel-Osco, Acme, Randalls, Carrs-Safeway, United, Haggen, Kings, Plated, Shaw's, Tom Thumb and Star Market. Shaw's and Star Market are in the Northeast and are operated as a single subsidiary.
