This depends on the seller you have bought the items from. If your items are consolidated and sent in one package, SendOn will treat it as one item. When buying more than one item from the same seller, we recommend that you ask the seller to send your items together as one single package.
When using SendOn USA or China items received in a single box or consolidated in the same box will be treated as one single item. Therefore customs, duty and/or Value Added Tax (VAT) will be calculated on the total price. It is recommended that items received in a single box/package will have one invoice declaring all items in the box/package.
