Magento Persistent Shopping Cart feature allows customer’s shopping carts to be persisted or saved across sessions where customer will be able to come back and finish the transaction. What this means is that, if a customer has added products in the shopping cart and then can come back later to complete the checkout process.
Standard Magento settings will preserve the items in the cart for a short period of time before it expires and looses all the cart settings. When the customer returns the next day for example, they will have to add the items to the cart all over again.
With Persistent Shopping Cart, when the customer returns tomorrow or even later again, all products added to the cart will be right there where customer will be able to complete checkout process. In fact, Magento will support persistence for customers across user sessions, browsers and devices.
Persistent Shopping, is now a well-known expression in eCommerce and Marketplace. It is a fantastic instrument to avoid the worst predicament of eCommerce Storefront – ‘Abandoned Cart’.
