Shop around, don't trade large sums of money to untrusted people and stay firm with your price. If a big gold buyer needs the gp they'll pay a little more to make a quick turnover profit. So all in all yes 0.26 is possible.
Very much possible, I've been buying for that amount all day.
just one tip:
DON'T ACCEPT PAYPAL PAYMENTS FROM UNTRUSTED MEMBERS.
Only accept PP from big shops, the names Feelgewd provided might be of use to you.
Good luck on your sale!
