You can create multi-variant offers on Allegro by grouping multiple listings of the same product that differ only by specific attributes (typically color, size, or weight).
Multi-variant offers allow customers to easily choose their preferred color or size without switching between separate product listings or sellers, which helps improve the shopping experience and increase customer retention.
Additionally, these offers typically rank higher in search results. The clicks and purchases from all variants are combined, boosting the overall popularity and visibility of the listing.
