I am happy to combine postage for multiple items if it saves you money. Just ask for a postage quote if you are not sure.
Thin items are usually sent at letter rate where possible for the cheapest postage.
My postage is at cost plus a few cents for packing or envelopes.
IN AUSTRALIA: 500g satchel with tracking: $7.50; 3kg satchels with tracking: $12.00. I also use the new 15 kg Australia Post flat rate boxes through click and send which are a great saving for multiple items.
IN AUSTRALIA: Buy as many books as you like - combined postage for books is capped at $15.00 - does not apply to bulk lots - ask for a quote first if buying bulk lots or if you are not sure. This offer is limited to the books fitting into a B4 box - AUSTRALIA ONLY.
