|Coupon Auctions Prohibited|
Some auction sites like eBay allow coupons to be sold on the auction block. I've never 'bought' a coupon as it almost seems like an oxymoron to me, but I guess one could still get a bargain by acquiring coupons that way.
However, have you noticed some manufacturers are now putting a stop to their coupons being auctioned? As an example, here's a coupon from one manufacturer getting their two cents worth in on the auction strategy, by prohibiting the auctioning of their coupons. Notice the coupon states, "May not be sold or auctioned, or otherwise transferred or reproduced." and this manufacturer considers it to be a form of fraud if their coupons are auctioned.
