Hello, I am interested in purchasing some of your designer bags, however, I have a few questions regarding them. 1. What is the minimum amount that can be ordered? 2. What is the return policy? 3. What is the shipping method? 4. What taxes, duties, custom, or brokerage fees, if any, will be incurred? 5. What happens if items are damaged or lost. 6. Are the bags authentic and if so do they have any defects or blemishes?
