I made a bit of confusion, sorry ...
The first time, when Ed30 bidded $15, without looking at the person who posted it for sale, in my mind I thought Ed30 was the seller who proposed "to sell it to me for $15" and now my "Ok" was to say, "Ok, if sold, no problem".
That's funny, all happened due to my imagination, ignore my messages, I'm very stressed cause I'm spending hours and hours working online lately
