Shopify Marketplace Connect

This app has enabled us to list at scale on eBay which we simply wouldn't be able to do otherwise. There's no magic bullet, you still have to populate some data elements for the listings from within Marketplace Connect, but it's so much more manageable when changes are synced across to eBay. A major bonus for when there are problems is the dedicated, knowledgeable support team within Shopify, with their own ticket system so you can contact them directly. For example when I recently had trouble working out some mappings, Mark L. saw the issue through to resolution and even fixed a related problem at the same time. Great work, thank you.
