Cost of domain

Website Domains cost vary based on what they charge, the only thing that is the same is the ICANN fee.
Why it is happening is based on what the Registrar decides charge, and all of their fees. In essence the registrars can all capture the domain for and then their fees on top of it. For keeping your domain, and offering you all of the services that they have to offer in their members area.
If you are looking for suggestions for Domain Registrars, I would suggest GoDaddy, I know some people would say bad things against them, but I have been with them for 7 years, and have never had any issues with them.
And depending on what you are wanting after the dot it is very cost efficient.
I know most people have different opinions of whom they would suggest, but this is my number one choice

Priceof domain dpends on registar. GoDaddy, Enom, Directnic, Directy are the biggest. They sell domain names wholesale and retail. Price by rtail is higher then price by wholesale.
Example
.com costs
Wholesale $5
Retail $12
All that companies has a lot of resellers
So reseller buy domains for $5 and sell for $7 for example with $2 profit by domain.
Better to buy domains from resellers.

I also think all depends on the registar itself. For example, you may reg a domain in .com for $8.95 per year from ahosting.biz. I think it's not expensive for this extension at all.

Has anyone found anything that NetworkSolutions provides that justifies them still remaining one of the higher costing registers? Yeah they offer all kinds of extra services, but all for additional fees?

Myself, I use PairNIC because I have been using Pair Networks for my hosting for over 10 years now and like keeping them all in the same company.

Much depends on the domain name extension IMO. For example, Valuhost.com offers domain registration starting at $10.
