There is a complete treasure trove of all kinds of Xena stuff online… but yes it can be tricky finding what you are actually looking for. I got the majority of the trading card sets, dvd fan kits, and a chakram and other random bits and bobs on eBay back in the naughties. I also attended the 2010 Xena convention and there was a lot of stuff for sale there…. I also eBay might still have stuff but I haven’t checked it out in a while. Good luck! Bear in mind - you have to pay for shipping wherever you are which can be a bit heavy!
