Bundling lets shoppers add multiple items from an individual seller to one bundle, with no limit on the number of items. Shoppers can make one offer on the full bundle. Like offers on single items, the seller gets a notification and a direct message with the offer amount, and can accept or counter. Shipping is automatically calculated and shown to the buyer before they submit the offer. Sellers do not see shipping costs; whatever offer amount is accepted is the total amount the seller receives before credit card fees. Note that bundling is only available when buying from individual sellers. When shopping from a business, you can add multiple items to a shopping cart instead.
