1 minute you save for Customers while shopping, a lot more sales you will gain! But default Magento always reloads page every time customers edit their shopping cart.
That's why you need Magento Ajax cart extensions to help you resolve this tedious process! Customers now can add product to cart and select its option right from listing page without going to product page. Besides, after adding product to cart in product page/listing page they can choose to continue shopping or checkout right away. Store-owner may show related products while Customers add a product to cart for up selling or cross selling purpose.
Many stores have implemented successfully this kind of extension and seen an incredible increase in conversion rate. Why don’t you start now before other competitors surpass?
