The cost for being able to point nameservers to a store/CART server is much to high. If cloudflare hosts the domain name then we should be able to point the Nameservers to whatever we like. Having to pay $200/month for the privilege is much to high for a SMALL BUSINESS. Pointing nameservers is a common feature in domain hosting.

Which ‘cart server’ requires that you point your nameservers to it? Can you share a link?
