I understand you are from a foreign country, and I respect that. But I believe people are not understanding your rules due to communication problems. You should change the rule of "I give offers,if it does over than 15$."
to
"I will only accept offers totaling over $15". I think you may get some more buyers with increased clarity. Just a suggestion.
Keen Player-You are from Finland,so that you pay with Euro.How much Euro do you give for it.15$ it´s O.K.It´s anything about 12 Euro.I´m from Czech Republic...it´s better for me.
