Keep your eyes open at your local Office Max for the $5 off coupons near/on the Sharipe and Expo products. In my local store the display was located near the registers at the front of the store. The coupon is good for $3/3 Sharpie and Expo products.
If you can find the coupon, here’s a deal for you:
Buy (2) Packages of Expo Dry Erase Markers $5/2
Buy (1) 4-pack Sharpie Highlighters $1
Use $5 off coupon
Final Price = $1.00 for all (3)!
