$3 off a purchase of $3 or more good through June 11. If you need ink, this might be a good time to buy. Staples is offering double rewards (20%) when you buy $50 of HP ink and recycle on the same day. You will also get $4 back per recycled cartridge (regularly $2). You could also use the $3 coupon to spend on select office supplies that are marked 50% off or more. If you received the Office Max fill a bag coupon for 20% off, Staples will honor that coupon. So, you could save 20% off your ink purchase, get 20% back in rewards and earn $4 in rewards per cartridge recycled.
See you at Staples!
