Hello!
i have not personally sold any of my Hermes bags on ebay but have sold them through almost all of the re-sellers, including: createursdeluxe, hermes**, jemznjewels and luxwear. This is my experience:
createursdeluxe: She offered me a price for my bags and the price was VERY low. I was desperate at the time so took it. I would not do this again.
hermes**: She charges 1k for a leather bag and 2k for exotic bag to sell. This worked out good,the bags sold fast.
jemznjewels: You negotiate a price with her and she posts it on her site. I found the price that the bag finally went for to be low. I could have stayed higher but it sat out there forever so I just wanted to sell.
luxwear: She charges 20% of what she sells the bag for. You negotiate a price you feel comfortable selling it at.
