H E R E - Info From the FTC is a link to the Federal Trade Commission's Consumer website. Scroll down and there is information on what the liability limits are. Past 2 business days but less than 60 calendar days, and the liability is maxed at $500! And if one doesn't find out until more than 60 days out, the loss is not covered, and one is out the money.
Simple reason to only use credit cards for such transactions; liability limitation is always $50, per the Fair Credit Billing Act (FCBA). Not so with debit cards, which are essentially an ATM card.
