The idea of SOs is a good one, but not when they change the game after you purchase. I purchased two SO Kindles last year. Afterwards we went from often receiving $5-$20 gift cards with purchases and great deals like that to receiving only local deals from stores we don't shop at and that sell things we wouldn't buy, especially at the inflated prices they wanted. Come on, a small box of cookies for $15 with the deal! And in my case, the local stores were all 20+ miles from my home. In the USA we call that a "bait and switch" and we take a very dim view of that underhanded business practice.
