Magento is a big advantage when it comes to e-commerce if your website’s retail business is struggling to control costs because Magento is an open-source solution used for e-commerce applications. Yes, the big retail websites do use this system which was formerly owned by the Varien company but if you are a small player trying to compete against the big boys then every cent you save counts in the long run. Because of this even major auction site eBay recognizes the usefulness of being associated with Magento (eBay has already bought out 100% ownership of Magento). So maybe you should too as well.
The Magento! Extension Directory offers more than 6,000 commercial and free extensions that you can use or you can turn to other sources to get even more extensions if you prefer.
