Netfirms is 4.99 per year but you need a credit card. Godaddy is 6.95 a year with a commonly found coupon (search online, easy to find). These are USD. ooh. Just saw you wanted 10. That'd probably be a bulk order in godaddy, so you're looking at around 5 - 6.

GoDaddy... it's always easy to find discounts, and they give you a discount for buying in bulk. Even more so, their interface is the best BY FAR.
