Coupon Clipping & Self check out counters - What do you all think --

Coupon Clipping & Self Check out
Most stores have self check out these days.
So what happens if you carry a coupon for say a 2$ off Gillete razor cartridge or 50cents off a tooth paste to one of these self check out counters
The machine reads - Do you have any items under your cart ? ( Who carries a large cart to a self check out register - none - mostly we carry under 10 items we are lazy lets admit - big cart.....we want some one else to ring us up, we dont want to do it by ourselves)
DO YOU HAVE ANY COUPONS ?
You say YES, please scan coupons, Scan your Gillete 2$ coupon it takes it off your bill,
Please deposit your coupon in the box ( you are supposed to put your coupon in a collector)
So im like why dont i put a small piece of paper in it and see what happens - tear the top part of the coupon some useless piece of paper and put it in the coupon collector
DO YOU HAVE ANY COUPONS ?
Say yes and use your same Gillete coupon for another razor or cartridge
I think you get the message.....
Im not for advocating some crazy coupon misuse scheme ....
But check it out next time you are in a 24 hour harris teeter or BJs or safeway or any of the other selfcheck out friendly stores
You may not be that lucky in Costco - they dont take any other coupons except for theirs so dont try there, you can eek a DIME out of that store !!!!!!!!!
