Whether an Internet hosting account meets the system requirements of your sites and how easy it will be for you to take care of that account are two quite important things. If you experience any problems or your sites just can't run on the web hosting platform for the reason that they were designed to run in some other system environment, it would be rather inconvenient in case you cannot get a complete or prorated refund and a lot of providers out there have such policies. Thus, you will end up losing cash as you will not be able to use a service you've paid for. To be on the safe side, you'd better check the refund policies of any company before you buy an internet hosting plan, so in case you cannot work with the account or simply decide that you do not want to use it for any other reason, you can request a refund.
