This is one special coupon of GoDaddy, not only for all services, no minimum, but also can be used for renewal domain or hosting. I often use this kind of coupon for those which rarely have discount program such as: VPS hosting, Server, Email hosting…
Besides, the coupon is available for renewal, so get it to renew your hosting which is about to expire in the near future. I rarely see any hosting provider has renewal discount coupon.
Good luck !
