Related Products, Up-Sells, and Cross-Sells
You can use product relations to create links between products. After doing so, one product displays other linked products. To add a product relation, you must choose from one of the available relation types. Then you can use a product publisher and choose the appropriate relation type to display linked products relative to the product featured on the page.
When placing multiple product publisher widgets on a product detail page, multiple sets of related products may appear. For instance, one widget can display alternatives while another can display accessories to the product featured on the page.
Here is a list of product relations that come with the Minium and Speedwell site initializers:
Up-Sell: products with a higher sale value comparable to the featured product.
Spare: spare parts or components of the featured product.
Related: a catch-all set.
Accessories: add-on products for use in conjunction with the featured product.
Cross-Sell: products complementary to the featured product.
