Wait until the GoTY Edition comes out, as it has an MSRP of $50, the separate packs are sure to drop somewhere. Right now though, they're 800 points each on the Marketplace and full MSRP for the retail packs ($20 for Operation: Anchorage/The Pitt, $20 for Broken Steel/ Point Lookout, $10 for Mothership Zeta) pretty much everywhere else, that I know of.
