using coupons correctly

There's been a lot of outrage among the couponing community at the fraud committed by a participant on the first episode of the current season of Extreme Couponing.  Since so many of you who are following my blog are new couponers, I wanted to just be sure to address the fact that #1-photocopying internet printed coupons is not OK.  Each coupon has a unique code, and if 2 coupons show up in the clearing house with identical codes, the store will not get reimbursed for those coupons, which is essentially theft.  Please don't do it.  And #2-you may have heard some hub bub about coupon coding.  Please just be sure that when you are using a coupon that you have read the wording on the coupon and are using it on the item the coupon was intended to be used for.  While the picture is not necessarily representative of what the manufacturer is allowing the coupon to be used for (they put a picture of their expensive items, hoping you'll buy those), the wording does indicate how you should be using that coupon.  Just because it will work doesn't mean it is ethical or legal.  I don't want to go into too much detail about this whole thing because even as a seasoned couponer, I didn't really know the ins and outs of what it is I am talking about until recently, so please just read your coupons.  If you have questions, I can maybe elaborate on an individual basis.
