a. five black & white composition books, wide ruled
d. five blue main lesson books, medium wide
I was shocked to discover that the Prismacolor pencils were $27.99 at Staples and $57.99 at Hobby Lobby. (They're $14.99 right now at Amazon.) So check! Composition books are fifty cents everywhere because people have price-matching guarantees, but the same is not true of the nice art supplies. If you are in the store and realize H.L. is ripping you off, look up hobbylobby.com on your phone and they always have a "40% off a full-price item" coupon which the cashier will scan for you.
A Child's Dream Come True, which is where we got our MLBs, is offering 10% off all their art supplies (and this includes main lesson books). The coupon code is ARTS10 to save 10% off all of their arts & crafts supplies.
