Normally, domain coupon of GoDaddy can’t be paid by PayPal. There’s only $7.99 discount coupon is valid with this kind of payment method.
$7.99 is a little bit higher than the general price level after discount. However, if PayPal is the only one option for you, this coupon is also the best choice.
I’ve got some discount coupons which can use PayPal to pay. Get them on the links shown below:
Good luck!
