I've compared pretty much every cart app available, and this one is AMAZING - so feature-packed, best user experience, excellent customer service (Isagi was super efficient and always willing to help)... I highly recommend this app.

An excellent app—it has everything you need to configure your Cart, with options to use a template or set it up yourself. Most importantly, I have never experienced such great technical support; it’s truly wonderful how they handle my requests step-by-step and resolve them in a matter of minutes—simply fantastic! I highly recommend it; you won’t regret choosing this app.

App muito funcional para o carrinho lateral e integrar produtos complementares. Só a questão de integrar com o APP de frete que não está disponível, porém, o suporte está buscando solucionar.
