Staples Teacher Appreciation Day is coming up soon. Typically they have one day in July or August for each store. Teachers get to go in and get a thank you gift bag and coupons. The bag is limited to the first 100 teachers.
I checked and the date in my area is 8/11 so you might want to mark it on the calendar. You can check and see what the date is for the Teacher Appreciation Day in your area here.
