If you're serious about eCommerce, and plan to have a highly successful website, then you should register your own domain. A Domain Name becomes your BRAND name on the Internet. - choose a name that is easy to remember and type in.

You can register as many versions of your domain as you wish. As well as yourname.com, also register yourname.net and yourname.org. Then you can register different spellings of the name, hyphenated forms and so on. If you don't register these, someone else will take them and the corresponding share of misguided traffic!

Do not register a name which is someone else's Trade Mark. If your domain name infringes on other party's registered Trade Mark, you could be sued for infringement!
