Buying a domain can cost you anywhere from $1 to $1 million, but no matter what you spend, it’ll probably be the cheapest part of your online presence.
So when I see people who definitely know better about GoDaddy and bulk domain registrars in general use the excuse that they had a $1 sale on, or whatever other reason, I can only think “A domain can be cheap but your reputation is priceless, so start using your head not your discount vouchers”.
If you are picking your domain registrar, the people who control your most important asset, on the basis of price alone, frankly you’ve got nobody else to blame when things go wrong.
Full disclosure, my company Nutmeg Data is a UK domain registrar but we don’t deal with the general public and I would recommend Domain Monster or Gandi if someone asked me.
