"I just want to let everyone know that I'm sorry for what I did and I take full responsibility for my actions," Anthony, 23, told the judge, referring to the check fraud. "I wish I would have been a better friend."
Surveillance cameras had caught her using the checks to buy beer, food, lingerie and sunglasses at an Orlando-area Target in June 2008.
She was sentenced to 412 days of time served in jail and one year of probation and ordered to pay $348 in court fees and $5,517.75 in investigative fees.
Anthony remains in the Orange County (Florida) Jail on charges that she murdered her toddler daughter, whose body was found six months after she disappeared in June 2008. The trial is expected to begin in the fall.
