From the image you provided, it is obvious the registrar is Porkbun. So, do you provide a 100% discount code redeemable in Porkbun ?
Since you are selling on a auto buy platform, will one get the code from there instantly and buy from porkbun or there is some other way ? And the biggest question is, what happens if the discount code does not work ?
Yeah, I will give 100% discount code, no I will send you code after purchase. I guarantee that Code will work or 100% money back (excluding fees).
