The refund policy of every web hosting company you choose is quite important because there's always a possibility that the service might not cover all requirements for your script-driven apps to work efficiently, you may have difficulties to manage the account or you might simply decide that you don't want to use the site anymore if, for instance, you see that it is not doing very well. In any of the abovementioned cases, you will lose your money if the hosting provider doesn't give refunds, even partial ones. In this light, checking the refund policies of each and every company you consider to register with will be a warranty that this won't happen. The policies vary from one company to another and a refund may be offered for different time periods.
