I totally agree with you... if you cannot sell an item back to Plarium, you cannot use it and you cannot donate or trade it to other players then there is something wrong with the mechanics.

I have not experienced this issue with the Caduceus yet as my elixirs are only level 7 & 8 at this point but I have with other items which I believe should be sell able/trade able.  Unused articles are somewhat in the same boat as Plarium offers very little for them but at least you can send them to other players free. I have a bunch of PP renewals that I will NEVER use because since level 35 I have been unable to clear the PP board. I guess those items were intended for early levels when PP are a significant part of your daily game and you easily clear all of them.

they come as "free" extra items :))) so you technical don't pay for these extra useless items which comes with packs. But in reality u pay top dollar for them :)

good idea to sell back item, usually games does it for 1/4 price or so, half would be great

my position about elixir stand thought, remove caducei all together or reduce price 10 fold.

Suggestion : add the ability to mix, for instance, 10 silver caducei to change them into 1 golden caduceus ?

Also, I agree unused (or accidentally bought, since there's still no confirmation) items should be refundable for half their price (or even less, but at least some drachmas). At least the ones from the "Special" tab in the "Misc." section, please.

It was just a suggestion, but the rate can still be debated. :)

You have to consider it's a gift feature, so the higher the rate, the higher the chance they may consider the question. ^^

Maybe a 1:5 rate or something like that should still be better than nothing ! :p

The existing "Amphora Chamber" tab could be used, so the modifications would stay as slight as possible. Since the caducei are displayed there already, the only change would consist into allowing to select them (and of course perform the merging). :)

Could trade dominion points as well   

The reason why they don't allow us to sell stuff is that they know pertinently that their value is far below their price...
