I have purchased a flap from supposedly trusted IG seller. The bag was described as "mint" with "minor signs of wear on hardware only". I paid about $5,500 for the bag. The bag I received had dirt all over the leather strap which never was shown or described. It also has a lose thread on inside flap. Once I contacted the seller she offered me either $100 refund or would accept a return. The bag in this color is very hard to find and I was looking for a very long time to get it. I got a quote from Leather Surgeons to fix the strap only (I've noticed a lose thread later). Leather Surgeons can fix it for $220 including shipping. I asked seller to cover this cost and then I would keep the bag. She refused and gave me her original offer $100 refund or return the bag. What is your opinion about this situation and how do you think I should proceed? I really want this bag, but feel it is unfair that I have to enquire extra expense for something that was misrepresented by the seller.
