I've had several bags repaired at LV and I have never heard that. They usually quote me right then and there. The bags have taken anywhere from 4-8 weeks for the repair to be done. I will also say in my last several visits to LV the customer service is not what it used to be!
That was what I was thinking, like really 4 weeks to just give me a price? And I also asked if I could get the bag back after the pictures were sent off but no that wasn't possible
