I offered 2700$ for a boat (via email). The seller took some time to respond to my offer, but eventually responded via a text message "We're good, he [his boss] said yes" (I was buying it from a non-profit, the director had to approve the deal). He never was willing to set up a time to do the deal, and I came to find later that he was still soliciting offers from other buyers on Craigslist and even said at one point that he "had not accepted any offers yet" and thought he could get more than he initially listed it for. Did we have an agreement? Is he obligated to sell to me? Does my text and email evidence stand up in court?And, at this point he is not returning calls, emails, texts, etc.
