No they do that without raising the price first. Mine in the order are 82.- Now there is the blatant discount to Chf 78.20. And look: Instead of Chf 89.-. So they became Chf 7.- expensive and at the same time there was this discount. Unfortunately, you feel like you've been had or cheated. What is it exactly? I don't know, but I definitely don't think it's ethical.

My tip: Compare, compare, compare.....regardless of what the discount says.
