Here are some tips when purchasing a domain:
- Look for coupons and discount.. hint: watch godaddy cool videos and wait... just by wtaching they will give you a discount..not bad eh?
- Search a domain that you like, if it is available, buy it! Don't hesitate. The chances of this domain availability is very slim once you let it go.
- Buy it for two year.
Please don't ever buy domains to untrusted sources! Although they offer cheap domains, the problem is, some provider don't allow renewal of contract, specially if the domain name already made its mark on the internet.
Lastly, if the domain you like is not available, don't go jumping on .net .org and other .something domain. Trust me, marketing wise, it won't do you any good.
PS.. domain in godaddy starts at $7.99 (that's with a discount, don't worry the videos are great!)
