ScandiPWA supports the display of related products, up-sells, and cross-sells on the storefront:
Related products are meant to be purchased in addition to the item the customer is viewing. Learn more about Related Products.
Up-sell products are items that your customer might prefer instead of the product currently considered.
Cross-sell items are similar to impulse purchases and appear in the shopping cart page, just before the customer begins the checkout process. Learn more about Cross-sells
