Hosting
What you pay for your hosting iss closely linked to the purpose of your website. If it is an informational site then it only requires a light plan.

For businesses requiring a catalog, online ordering or online shop with large volume of site visitors each month an ecommerce package is the best option.

Similarly if your site has any sales or promotion videos then the site will need a hosting plan with sufficent monthly download limit to cater for an expected high number of users and large amount of bandwidth.
