I pay $11.99 but because I have so many domains they throw in Discount club for free and my .com's are about 10 bucks.
I could save a buck but the discount club gives me a number of perks with auctions etc and that has worked for me so far.
In all seriousness though, will probably be renewing them at Dan because they are saying registrations there will be at cost once they go live as a registrar. The only drawback will be having to pay in USD because the credit card companies always mark that up a bit.
