A typosquatter is someone who has registered a web address that is very similar to a well-known shop or online business. The difference can be a common or simple typing mistake. So, for example debenams, or argoss have been seen. The criminal then puts up a web site very similar to the real shop in order to entice you to enter your credit card details. It is usually a good idea to type in the name of a web address in order to avoid clicking on a suspect link, but this scam shows you have to be very careful not to make any mistakes. If you are in any way suspicious about the site don't leave your credit card details.
