some domainers like to purchase right away and mull over it for a few days and possibly delete it and get a refund if they change their minds. others like to do a little research first and then open their wallets.
For domains without fees to refund, like us and tv, register any domain you search, and, after the grase period, refund all without traffic
For the others with little fee, I prefer to make a litle research =p
i had registered a few which i thought were excellent, symbolic of my brainpower....until i brought it up to the forum and it turned out to be just ordinary
so i need to trust someone or something outside of myself...and i read more on this forum and try to digest it...for example, reece here said that estibot is good for estimating 4-character .com only and so i am taking it seriously
Qu: when should you buy a domain?
Ans: when the experienced forumers here said it is good
