Our verdict
Shift4Shop (formerly 3dcart) offers a full-featured e-commerce platform completely free for US merchants who use Shift4 payment processing. It includes features that competitors charge premium prices for. Best for US merchants committed to Shift4 payments. The main caveat is locked into Shift4 payment processing, dated interface, and less polished than Shopify.
