When buying a lot from Yahoo! Auction Japan, you pay on top of the auction base price our Company's commission, the cost of delivery to our warehouse (sometimes there is free shipping, depending on the seller), and consumption tax if a seller charges it.
Standard consolidation service is included in our commission. There's no need to pay an additional fee if you want to ship your purchases as a single package.
Additional charge for consolidation and re-packing of heavy and fragile goods is a subject to agreement. Please contact your manager if you're planning to purchase anything heavier than 10kg.
