The refund policy of each hosting provider you choose is quite important as there is always a probability that the service may not cover all the requirements for your script-driven apps to work properly, you may have difficulties to manage the account or you might simply decide that you don't want to work with the website anymore if, for instance, you see that it is not doing very well. In all of these cases, you will lose your money in case your web hosting provider doesn't give refunds, even partial ones. In this light, checking the refund policies of each company you consider to register with will be a guarantee that this will not happen. The policies vary from one company to another and a refund may be offered for various periods of time.
