I don't like the Swisscom exchange. Whether you buy for Fr. 49.-- or Fr. 500.-- you only get a single discount of Fr. 20.-- and not in increments of Fr. 49.-- as all shops do during various promotions. My son was taken in and is very disappointed with Migros. He was able to exchange Coop points for a computer at Interdiscount without having to pay any money. Too bad for students who try to find the best deals. We'll go elsewhere next time
