He estado usando Stack con 3 módulos habilitados y honestamente... simplemente funciona. Fácil de configurar, mejor precio que las alternativas, y el soporte resolvió mi problema en 10 minutos. Super recomendado ayuda a facilitar muchas acciones de tu tienda

Installing Stack was such a game changer. Everything instantly became more organized and way more clear for customers. They can see every discount applied, every offer they qualified for, and it all updates in real time without any weird glitches. No more frantic emails from customers asking why their discount didn’t show up!
