Isn’t it common to walk into a store for one product and walk out with more? You may have planned to buy just one item, but ended up adding a few extra things because the shopkeeper suggested something useful at a discounted price. That’s exactly how Shopify in cart upsell works in an online store.
For example, you might visit a store to buy a laptop but end up adding a laptop sleeve or a wireless mouse because it completes your purchase. This is what an upsell looks like in action.
In cart upsells show complementary or related products right inside the cart, at the moment when the customer is already ready to buy. The offer feels helpful, not pushy - and that’s what makes in cart upsells so effective.
In this article, we’ll look at the best free and freemium apps for Shopify in cart upsell. I’ve included both in cart upsell apps and cart drawer apps.
In-cart upsell apps work with your theme’s existing cart or cart drawer and let you show upsells without changing how your cart behaves. They’re simple to set up and help increase your average order value with minimal effort.
Cart drawer apps, on the other hand, usually replace your existing cart drawer and come with more advanced features. Depending on your theme, they may or may not be fully compatible.
I’ve personally tested each app in my development store and shared my honest experience, so you can choose the one that fits your store the best.
Shopify says, Cart upsells can drive 15-25% of monthly revenue when optimized, with relevance and timing as the key levers.
