Freight shipping model. Available only for the US, UK, AU, CA and CAFR sites, and only for domestic shipping. FreightFlat applies to shipping with carriers that are not affiliated with eBay. It is negotiated freight, not a flat rate. Sellers negotiate the shipping cost with their chosen carrier and the buyer before completing the sale. FreightFlat shipping may be used when calculated shipping cannot be used due to the greater weight of the item.
