Back-to-school bargains are here, so stock up on these Staples deals while you can! Do be aware that weekly deals are available while supplies last, and not all Staples locations take manufacturer coupons. Prices are valid 8/6 – 8/12. Grab a copy of this week’s ad for a hot 20% off coupon that is valid on all office supplies, including backpacks. Grab the ad all week long at your store (usually located at the front entrance).
