Online Organic Coupons

I searched online for more place to find organic coupons and came upon something I thought was rather funny. Organic coupons were being sold on ebay. That's right sold on ebay. Now isn't the purpose of coupons to save money? So why would a person spend money to save money on organic food. For example, if you have a coupon that saves you a dollar off the product, why would you pay 99cents plus shipping cost for this coupon. You aren't saving anything. Naturally most of these offers had no bidders, but every-now-and-then I saw a few. Of course these were for offers of multiple coupons in one bid, plus free shipping. This makes a bit more sense, but still I would worry about the coupon expering before it arrives. What do you think? Would you buy coupons on ebay?
