Folks love Shopify, and it does work very well. But for my small businesses I've been very happily using Woocommerce on Wordpress, basically nothing but the hosting cost for Wordpress, and it's been delivering very well. I've done several million annually on the Woocommerce / Wordpress combo.
That being said, even eliminating or reducing Shopify would still have you at a premium vs last year so there must be some other Saas / Cloud expense driving that bill up.
