what's the lowest price in which we can buy a domain name

[indieover]

well yes it is much cheap in iDotz
it is $8.95 per year for .com while it is 9.99$ in godaddy
but godaddy is of best reputation than others
maybe i will condsider iDotz in the future.

is it really $8.95 only per year. and no other cost like monthly cost and etc. when i buy a domain do i need freehosting. well i really don't know if my domain will work if i just buy a domain only.
