Looking for some inexpensive entertainment this weekend? It’s HBO and Cinemax free preview weekend at a number of major cable providers, including Charter, Comcast, Cox, Time Warner, and Verizon FIOS. If that doesn’t include you, keep an eye on the FreePreview.tv site to learn when your provider’s previews are coming up. [FreePreview.tv] (Thanks, Tim!)
