Just got a renewal notice for Buxr.com domain and it had this coupon code in the sidebar. Enjoy!
Here is the fine print that comes with it: "Not applicable to ICANN fees, taxes, transfers, premium domains or Search Engine Visibility advertising budget. Cannot be used in conjunction with any other offer, sale, discount or promotion. After the initial purchase term, discounted products will renew at the then-current renewal list price. Offer does not apply to renewals."
