Overview
Upsell products may have one or multiple variant options (such as size or color). AfterSell handles out-of-stock variants differently depending on how many options a product has, to ensure a smooth customer experience and prevent unavailable selections.Out of Stock Variant Logic
Products with a Single Variant Option
If a product has only one variant option f that variant is out of stock, it is hidden entirely. For example,-
The blue variant for this Notebook product is out of stock

-
Therefore, on the post purchase page, the blue variant will not show up as an option

Products with Multiple Variant Options
If a product has multiple variant options, all variant options are displayed, including those that are out of stock. By default, AfterSell will preselect an in-stock variant, if one is available. However, if a customer manually selects an out-of-stock variant, it will be clearly marked as unavailable and cannot be added. For example,-
The blue/small variant for this T-shirt product is out of stock

-
However, the variant will still appear on the live post-purchase page, but customers will not be able to purchase it if selected.
