WooCommerce cart addon comprehensive rules for cart cross-sells
Do not assume the shopping cart page means the online shopper has finished and is ready to checkout. You should always show cross-sell items, especially on cart views. People access the shopping cart for any number of reasons, and adding recommendations to your shopping cart adds another layer of interest for buyers and helps add value to their buying experience. Most store owners want to get the customer to the checkout process as quickly as possible. However, studies shows show that placing recommendations in the cart have garnered higher conversions versus carts that dont have recommendations in their cart.
The Cart Up-Sells extension is a powerful tool for driving incremental and impulse purchases by customers once they are in the shopping cart. It extends the concept of up-sales and cross-sells at the product level, and engages your customer at the moment they are most likely to increase their spending.
