I am looking for an extension that can help customers to add many products to cart in the category page. It means that they do not need to visit each product page as normally because it takes much time.
Is there any extension like that?
You can check out this extension - https://www.magentocommerce.com/magento-connect/ajax-shopping-cart-by-amasty.html
It helps to add products right from the category pages without unnecessary page reloads.
If you are using Magento 2, Add Multiple Products To Cart for Magento 2 by BSSCommerce allows customers to add multiple products to cart right on category pages or search result pages and even homepage.
The module supports these following features:
Hope it can help you with your business!
Thank you for the extension for Magento 2 @emmanguyen. I have been using extensions from your team for a while. Always satisfied about them!
