If you get an internet hosting account for your sites, you could learn that it does not match some requirements that your script-driven applications have, or if your sites are not doing very well, you could decide that you no longer want to run them, so you may end up owning an account that you won't really employ. In this case, it will be good if you can close the account and receive your cash back as you will not be able to use the service for one reason or another. Some providers offer refunds - full or prorated, and others do not, so before you purchase a new account, it is good to check not only whether the service will match your preferences and requirements, but also what refund policy the provider has about possible refunds.
