It makes me wonder just how aggressively ebay will enforce it. I can see ebay searching the coupon listings for certain key words "free" or "get one", but will they go beyond that? Take the Pantene coupon. If it is listed as "Pantene coupon" and simply described as "from the 7/7 P&G insert"), that should be enough info for any buyer. Is ebay going to have people who know the coupons?
I suppose the CIC could spend the day searching for ebay listing that violate policy and report them. Then ebay would cancel them, it would give the president of the CIC and only employee? something to do.
