Im trying to sell my char for 50 coins, but warmane wont allow

Hi

I'm trying to sell my paladin forf 40-50 coins on trade section.
Warmane decides that pric should be 182 coins.
I try to but cheaper price but it just removes it and puts 182 price back.
I can put higher price than 182 but cant put lower.
Is this bug or?

Store items increase character price. Remove all items that can be bought from store and then you can sell your character for 30 coins minumum
