I share your frustration with the lack of response from the seller. Someone a little North of me has posted a craigslist ad for the same gulf sign 3 times in the last year (last summer and twice in the last month). I have responded each time (by email, the only option) that I am interested in purchasing the sign for the asking price, which I think is fair.

Never a response - just crickets.

Not sure if the seller is serious about selling, isn't getting my email or is just screwing around. At this stage, even if he were to reply, I'm not sure I would want to pursue it as I don't want to get caught up in a wild goose chase. Joe
