What's the best app for variant-based upselling on my ecommerce site?

[GrowthHobbyiest]

I want to introduce variant based upsell for my Shopify account. Recommend any relevant app.

For example, we have 2 pizza options Medium for $5 and Large for $10. When users add-to-cart the Medium option, we recommend them to purchase the Large pizza for a 10% discount i.e., $9. If the user accepts, we want to replace the current item with the recommended item at the discounted price.

Please recommend relevant app.

We have one app called iCart Cart Drawer Cart Upsell for this by which you can show upsell and product recommendations with special discounts like fixed amount, percentage, etc. Apart from this, you can show product bundle, progress bar to entice customers in buying more.
