Sam’s Club has a new free Purina One pet food link up. A membership ID is required, so bust out those Sam’s Club cards! You know, the ones with the nine digit ID number and a little black & white photo of you down in the corner. No, that’s your library card. Stop, stop, that’s a voter registration card. You know, on second though, how about I take that pet off your hands. I’m not sure you’re qualified to look after another living creature.
