In the US, we have what we call a "fairness exchange policy." If you bring your A8s to any of our showrooms we will sell you a new pair at half off. I don't know if you think that's worth it, but I fixed a pair of my own A8s once and wasn't really satisfied with the finished product. It's always an option.
There is scarcely anything in this world that some man cannot make a little worse and sell a little more cheaply. The person who buys on price alone is this man's lawful prey. - John Ruskin
