I remember selling my MSI GTX 1060 6GB for 13.5k(Just bcoz I had already committed) to @Krato$ 3months ago Even after people offering upwards of 16-17k on PM. He is yet to post the feedback and does not reply to pm's anymore.Since they agreed to deal then seller should honor his commitment but as we know its all about money, commitment doesn't hold merit VS Money (for some people only). As per business point of view, seller didn't get token money so he can back out. In my opinion seller should have been honest with the buyer and told him clearly that he is getting better offer so would like to go with second buyer unless he agrees to match that offer. Thats a fair point and buyer would understand since they didn't exchange money
