I know it seems a bit early for back-to-school specials being only mid-July, but they've been cropping up all over the place. Staples has started to run weekly specials. I missed out on some great items that were only a penny last week, unfortunately. I've also spotted great deals on spiral notebooks (15 cents) at both Meijer and Walmart.
We don't need a ton of supplies this year, but one thing we use a lot of that is hard to find on sale during the regular school year is composition notebooks. My daughter uses these for her math work, stories ideas, music lesson notes, etc. The cheapest that I can normally find them is for $1, but Walmart currently has them on sale for 25 cents each! I purchased 40 and am debating on whether I should go back for more. If you haven't already, now is the time to stock up on those supplies that you use all year.
