I own 7, 6 of which are developed.
I was just curious, see people that have hundereds, do they still have to pay the $~8 a year to keep them, or do they get them cheaper?
I actually have a few domains that I have registered for 10 years, so I got a huge discount on that. I'm slowly moving my "main" sites towards that direction. I cannot speak for others though. You also have resellers who pay around $6 per domain name.
