Josh from Victoria had been speaking to Eric from NSW over the holidays. Eric had said he was considering selling his guitar for $500 in the next few months. The guitar was at his sister's place in another suburb. After a few weeks Josh texted Eric and said "I'd like to buy the guitar that you mentioned for $500. If I hear no further from you, I will consider the sale complete" Eric was happy to sell to Josh. Eric's sister in the meantime had sold the guitar on the internet to Bryan. Advise Josh
