As part of the national small business week celebration, staples is giving Scratch game cards to customers. These cards can reveal 15-50% off coupons that can be used in store. I got a 15% off in-store purchase coupon. Usual exclusions apply(doesn't work on computers, gift cards, tablets ....). It is limited to one per customer per day. These coupons are good between 06/01/12 -06/30/12.
Edit: The % discount is off of a single item( I am assuming it works on multiple items if they all have the same SKU just like the staples app coupons)
Edit: Attached picture of the scratch card game as proof
