Managing Domains

[lcubehost]

I have looked around some on the forum, so I hope I am not repeating something already addressed. I have a question about managing domains. I figure you could just use a simple spreadsheet to do this, but my main question is about registering across multiple registrars. Is it a good idea to do that? For example, sometimes a registrar will have a special on domain names that beats your usual registrar and you want to take advantage of that. Does that become too cumbersome? Also, I am a WWD reseller, and I feel compelled to purchase from them, however sometimes other registrars still have better offers; particularly on .info domains.

Thanks in advance for the help
