Hi, I am new to all this and I'm about to pay a fortune for my first dior gaucho tote in winter white. The bag is about to be listed on eBay, by a 100% positive feedback seller http://myworld.ebay.com/beautifulbasics so far, great customer service and communication. the bag is in a mint used condition with its medallion missing...offered price is a little over $1000 with shipping. currently my only concern is the seller's no refund policy and the missing medallion. would dior boutique replace it for me with a fee? and is this bag authentic? is the price reasonable? is it worth it or not worth it...i need everyone's advice. specially dior gaucho owners, your response will be greatly appreciated. I've attached some pictures, and thank you everyone!
