The HH bags that I love have beautiful leathers and intricate detailing. If the sales ceased permanently, I would most def. purchase at full price. FWIW, I do believe that once they become "mainstream," the prices will increase as they all seem to do.
Completely agree with you and would also be willing to pay full price. I do it with Coach and Balenciaga, etc., because I love the bags and without blinking-- and then I see those bags everywhere. I take a lot of pleasure in supporting a small, new business (and of course I also like it that they are in my 'hood!), and in knowing that the bags I carry are unusual.
I think the HH brand will become well-known-- and not too far in the furure, either. One of these days HH bags will start appearing on the arms of celebrities and we'll all have the pleasure of knowing we were there first. Not to mention how smug we'll feel about the prices (sale or full) we paid "back in the day."
