Choose the Right Supplier for Each Part of the Offer
Your best gift may not come from the supplier that provides your main product. Select the appropriate supplier variant for each item, whether the products come from one supplier or different suppliers. For every supplier item, specify the variant and number of units required by one purchase of the offer.
For example, a lipstick can be paired with a lip liner from another supplier, while a “buy one, get one” offer on the same lipstick can use one supplier SKU with a quantity of two. The first setup needs separate supplier components; the second needs the correct combined quantity. Both keep the customer offer tied to the items you intend to source.
