I would suggest MyDomain.com with the coupon "bargaincat.com" for $7.61 for registration & renewals while transfers are just $6.79,
Why do people always look for the cheapest provider? Cheapest is not always best, instead it mean worse sometimes.
Price lists are on Domparison, check the link in my sig. Some of the prices need updating since ICANN upped the fee by about 40 cents though, will try and sort it all this week.
http://www.innovativedomain.com/how.html is one of the cheapest I have seen. I do not know if they are reliable actually.

Depends on what extension you're after. Always use well known companies - either GoDaddy or Name.com are the best. GoDaddy has $1.49 .info's and $6.99 .com's (just search "Godaddy Coupon" in google to find a coupon. Name.com is the best all round, but a little more expensive (only by a few dollars)
