Why pick Shift4Shop?
Shift4Shop (formerly 3dcart) offers a deep, feature-rich platform that becomes free if you process payments through Shift4. That bargain comes with dated interfaces and a payment lock-in that does not suit everyone.
Best for: US sellers who will use Shift4 payment processing

Substack makes launching a paid newsletter effortless, bundling publishing, email, payments, and a discovery network at no upfront cost. The flat 10% revenue cut is significant once you scale, and you build on their network, not your own.
