Absolutely!!!! Federal law limits your liability to $50, and even that is normally waived if you report the problem promptly. A credit card is the only realistic way to purchase your wheat and gluten free food on-line. Obviously, you can't send cash. If you send a check, you give people all the information they need to clear out your bank account. Personally, I would not use a debit card. The rules are essentially the same, but a person who has that card number has the power to make your life really inconvenient. I use two credit cards — one for my on-line activities and one for everything else. That has nothing to do with security, it just makes it easier for me to compare my receipts with my card statement.
