The refund policy of each internet hosting provider you choose is really important because there is always a possibility that the service might not cover all of the requirements for your script-driven apps to run properly, you may have difficulties to manage the account or you could simply decide that you don't want to work with the website anymore if, for example, you see that it's not doing very well. In all of the aforementioned cases, you will lose your money in case your hosting provider does not offer refunds, even partial ones. In this light, taking a look at the refund policies of any company you consider to register with will be a guarantee that this will not happen. The policies differ from one company to another and a refund may be offered for different time periods.
