Need all of your help to decide!!! I have gotten a jumbo flap with new chain from a Chanel Boutique from the States. But the hologram sticker was nowhere to be found inside/outside the bag when I opened the package to check everything. I have talked to the SA and after confirming the sticker was really not in the bag, their store offer me a return and refund or keeping the bag with 15% off and free shipping. What would you do? Keep or return?
