Shared hosting is web hosting in which the provider houses multiple sites on a single server. For example, Site A shares the same server with Site B, Site C, Site D, and Site E. The upside is that the multiple sites share the server cost, so shared web hosting is generally very inexpensive. In fact, you can find an option for less than $10 per month.
The 30-Day Satisfaction Guarantee applies to new orders for Web Hosting and to existing customers who upgrade to Web Hosting from Domain only or standalone Business Mail accounts. Subject to the following limitations, you will receive a refund from of your Web Hosting fee (other than the domain registration charge), including any setup fees actually assessed, if you are not completely satisfied. Included in your Web Hosting fee may be a required yearly domain registration charge. Domain registration is arranged on your behalf with a third party following placement of your order and cannot be canceled by that third party (your domain can, however, be transferred to a new provider after 60 days). The associated domain registration charge is nonrefundable - even if you transfer to a new provider after 60 days. If the total Web Hosting fee paid by you is less than the non-refundable domain registration charge paid on your behalf, you will not be eligible for a refund under the 30-Day Satisfaction Guarantee. The Satisfaction Guarantee period starts on the date your initial order is placed. Claims for a refund of Web Hosting fees must be made within 30 calendar days of your initial order. All refund requests must be made by calling 1-866-781-9246 and must be specifically requested at time of cancellation. Refunds will be made only to the name, address, and credit card account on file. Refund does not apply to any add-on services, such as additional bandwidth, additional email addresses, or Private Domain Registration. See the Terms of Service for additional terms and conditions, available by clicking the link at the bottom of every page on our website.
I wanted to point out that you do not mention critical issues. One is that some of the Top 5 Hosting Services do not offer an e-mail account. Others charge $14.00 a year to transfer your a Domain Name and host it with them or else the domain owner does not get the hosting for free. The list of unpleasant conditions that render those top 5 Hosting Services substantially less appetizing than you painted the picture, and that list goes on and on.
Migration or transfer services are often free or offered at a reasonable fee. These services help move your existing site to the new hosting provider. They can save a huge amount of hassle. Just remember that the migration process is often automated, and may fit in with the host's processes and needs rather than yours. Not everything may migrate, and you may find the organization of the newly migrated site makes for harder maintenance in the long run.
