The refund policy of every hosting company you choose is quite important as there is always a chance that the service may not cover all the requirements for your script-driven apps to work correctly, you may have difficulties to work with the account or you could simply decide that you do not want to use the site anymore if, for example, you see that it is not functioning well. In all of these cases, you'll lose your money if the hosting provider doesn't give refunds, even partial ones. In this light, reviewing the refund policies of each and every company you consider to register with will be a guarantee that this cannot happen. The policies vary from one company to another and a refund may be offered for different time periods.
