FRIENDLY REMINDER: Pencil in towels at the top of the list of things often forgotten by college-bound freshmen. You don’t have to shell out a ton of cash for these essentials, however, especially during back to school season. For example, a handy set from Walmart’s Mainstays line is now only $20. In several bright, cheerful, absorbent colors, they’ll be the envy of all your friends who forgot to remember. GET IT: Six Piece Mainstays Towel Set; order online or check your local Walmart location for availability.
