A long time ago Network Solutions was the place to register domains for something like $30 a year (I can't remember), and Godaddy was the cheap, fast, up-and-comer. That's when I moved onto them, and everything after that was just an afterthought. I even got really good and completely ignoring the upsells and could navigate around pretty quickly. Some of it is legacy and if I was in the market for a first time registrar today, I may have chosen differently.
When I was moving all my GoDaddy domains to NameCheap earlier this year, I decided to go whole hog and take my Network Solutions domains there as well. I had about a dozen URLs with them, and at $35 a year, it would be worth the savings.
That's when I discovered that if you call Network Solutions in person, and tell them you're leaving for a cheaper registrar, they'll match the price. I kept my dozen or so domains there, and now have a locked-in price of $9/year with Network Solutions.
I still feel some loyalty to them from the early days when they were the only registrar. For some reason, I felt like they were more credible. I know they've actually got their own skeletons in the closet, but old habits die hard.
I agree with this. Plus GoDaddy you can always find domains for very cheap due to all of their "promotions" or "coupons". I've gotten so many $2 domains from GoDaddy that it's ridiculous.
But I moved my domains away about a week ago. No discount is worth supporting GoDaddy.
