I would say that here and eBay are probably your best bets with regards to selling. If you're having problems selling at the price you currently have them at, consider including 'Or Nearest Offer' on forums/sales ads; or 'Make An Offer' on eBay. Allows you to let people who are definitely interested make an offer a slightly lower price. If you're happy with what they offer, accept it, you'll both feel good.
Alternatively, if there are any Collectors' Fairs which take place within your local area, or a comfortable travel distance away, you could always try there. Trader tables are usually cheap or free (at least the couple near me are).
Thanks for the advice :')
I've tried both starting at ridiculously low prices, I barely cover the cost to get them (I live in the UK so no trading things happen here). We have to pay extortionate customs fees (£8 plus 20% of the price) so getting more than one deck can end up costing a lot.
It seems the market isn't doing too well for cards, I used to sell on eBay with decks not nearly as rare and they went for more than what I'm offering stuff for :')
I might just sell it in bulk really cheap to someone
