What are “mass-cut” coupons?

The term mass-cut refers to several coupons that were cut together using a cutting device, usually in large numbers. This is a common characteristic of coupons purchased through coupon clipping services — most if not all manufacturers do not allow their coupons to be transferred or sold.
 
Some coupon clearing houses will not redeem stores for any coupons that are deemed to be mass-cut. Due to this, our policy does not allow mass-cut coupons.
