The cost of maintaining Domains has gotten very expensive. A few years back with a coupon you could renew a Domain for around $5-6 but now its $10-$12 about double the price and the trend is that it is going to get even more expensive. Unfortunately, I have started 'cleaning' house with the aim of getting rid of domains that we really do not use thus letting them go into Pending Delete phase. Gone are the days when you had hundreds of domains, sub domains are more practical now.
