Buying a new domain name from GoDaddy is easy as long as you don't get caught up in their upsell messages (unless you want to be upsold!)
GoDaddy have lots of promotions and lots of coupon codes which you are supposed to input at the checkout stage
If you don't have a discount - just open another browser and search Google for 'GoDaddy Coupon' and you can choose the discount coupon that's right for your order
