The Blistex Moisture Melt lip protectant/suncreen is free after register reward at Walgreens this week. You pay $2, and you receive a $2 register reward good for your next purchase. I found mine on a little display on the counter in cosmetics.
It has a very slippery, light-weight feel. I think it smells like cotton candy. It gives your lips a shiny, glossy look, and it has SPF 15. I tend to like glosses with a slightly heavier feel, but I love the smell. It seems to be very moisturizing, but I haven't used it for long enough to fully review it.
