I know this may seem not so extraordinary, but the Dollar World in Wayland carries Diet Dr. Pepper. $1 + deposit every day. This is quite impressive, as I have never seen name brand soda at a Dollar store before (I don't really know why) and Diet Dr. Pepper is my mom's absolute favorite. When it's not on sale, it's about $1.59, so it's very convenient to have an affordable source.
