Any coupons for ".co" domain names?

Hello,

I am going to buy over 30-40 domain names, most of them ".co". Do you have a tip for some coupons? So far I found 30% off of the whole order by GoDaddy, is there something more advantageous?

Thanks

Well, here's the list of GoDaddy promotion coupons that I found: http://renewalcoupons.com/godaddy-promo-code/.
