Buying a new domain, such as Example.com or .net is pretty cheap, but the hosting is what can cost a lot, at least from what ive heard. But i have recently found a really cheap hosting site, to host your site. The cheapest one i have found is Hostgator.com , Its only $7.95 a month! Im planning to actually make a video about it later. Its what i will probably use in the future when i buy a site domain.
