LitExtension Store Migration

We used LitExtension for our BigCommerce store to Shopify. I thought this would be more of a self service extension rather than a service. I talked to their customer service agents dozens of times. If I had a problem they couldn't quite help me solve, they always had an alternate and good solution. This is a service, not just a tool and I am very pleased with how much they helped up migrate over 150,000 orders!
