Namecheap just announced that they’ll offer new .com/.net/.org domains for $5.99 and transfers for $4.99 during the rest of September 2010. Just use the coupon code ‘SAVEBIG’ and save a few extra bucks.
Personally, I can only recommend them – I’ve been a satisfied customer of Namecheap for years, never having any problems (though I’m only using their registrar services and can’t speak for their hosting products)
