Sorry, the Theraflu sample is no longer available. I can’t say I was excited to see the new Theraflu sample from Sam’s Club, because that means that the cold and flu season is just around the corner. Well, maybe it’s already here because I had a horrible cold last week. Thinking of Theraflu also made me think of these other samples still available that you might want to try: Emergen-C and Airborne. They both claim to help boost your immune system. My favorite cold remedy is hot tea, but it’s nice to try new things to see what will bring you some relief! That’s where free samples come in handy.
