A new spin on the old saying, "caveat emptor" -- let the buyer beware.
A survey finds most American consumers don't realize Internet merchants and even traditional retailers sometimes charge different prices to different customers for the same products. The study found nearly two-thirds of adult Internet users believed incorrectly that it's illegal to charge different people different prices. It's a practice retailers call "price customization."
More than two-thirds of people surveyed also said they believed online travel sites are required by law to offer the lowest airline prices possible.
