I have recently joined EPN and I have a doubt.

If an eBay seller has also an e-commerce website and join an affiliate platform such as CJ or Tradedoubler, can I promote that seller through such affiliation platforms as well?

I mean, besides the eBay listings, can I also publish banners and links of a specific seller which is already present on eBay?

Thanks in advance for any clarification it will be provided.
