ESTERO, Fla. - It should have been a simple transaction on the website Craigslist.

Robert and Wendy Williamson wanted to get rid of a refrigerator and thought the popular site would bring a quick sale and help them clear out their garage.

A few days after they posted the ad they got a hit from an eager buyer.

Later, Williamson got what looked like a 2 thousand dollar cashiers check and received an e-mail from the buyer giving instructions on what to do after depositing the note.

That's when the couple began to see red flags.

They took the check to their bank where they learned there were no funds to back it. Moreover they were told they were lucky they didn't deposit it.

Bank of America told WINK News funds from a deposited check may be immediately available. The check could take up to 90 days to bounce, leaving the bank customer responsible for the amount of the check's value.
