You really can only see about half the stack here. We've found Mondays the bins are stuffed full (not so good for us trying to empty our recycling, but I get tons of inserts!) And the inserts are from our local paper and from papers in the surrounding counties. Which means different versions of the same coupon (it may be $0.75/1 in one paper and $1.00/2 in another) or even different coupons all together.
So check your recycling bins! You might just score some free coupons!
