Whether a hosting account meets the system requirements of your websites and how easy it will be for you to maintain that account are two rather important things. In case you experience any kind of difficulties or your sites cannot run on the web hosting platform due to the fact that they were designed to run in some other system environment, it would be rather annoying in case you cannot get a complete or prorated refund and a number of providers on the market have such policies. That way, you will end up losing funds as you won't be able to use a service you've paid for. To be on the safe side, you should check the refund policies of any service provider before you buy a web hosting plan, so if you cannot work with your account or simply decide that you don't want to use it for whatever reason, you can request your money back.
