Magento's official extension store is built to provide all Magento merchants with a better selling experience. Only those modules which have been carefully selected via Magento Extension Quality Program are released on the Marketplace.
We are pleased to announce that M2E Pro is available on Magento Marketplace starting from v6.4.12. The Extension has successfully passed a rigorous selection process including the business, technical, and marketing review.
The Extension is fully compatible with Magento v1.5.1 and higher to provide numerous merchants who are selling via the Magento platform with the high-level service.
Using Magento Marketplace tools, the Module installation/upgrade executed automatically and does not require any technical knowledge for that. Detailed instructions can be found here.
