I'm pretty sure this is belong to Digital Goods.
Just like you told,i searched on retailmenot.com and got 93% off godaddy coupan but then found godaddy doesn't accepts bitcoin/pm.
I can only pay with bitcoins/pm so is there any way i can buy on go daddy using bitcoins (may be virtual credit card way?) Will it work?
As far as I know, you can deposit Bitcoin to your account at namecheap. Get a virtual card and try it yourself, it is cheap since you found a 93% discount code for GoDaddy.
