Just found this out yesterday so I thought I'd share it. We signed up for an account at Fatwallet, and we used their codes to get discounts on godaddy and we also got cashback on top of using the codes. We just bought 34 domains yesterday and our average cost was $6.80 per domain. I don't know if there's a better deal out there than that, but if there is I'd be glad to know. Wish you all the best!
