It is always cheaper to send one big package than a few smaller ones.
For example, three 4 lbs (approx. 1.8 kg) packages can be shipped to Australia for 3 x $69.60 = $209.90 using USPS Priority mail. At the same time you can combine your purchases in one box and send one 12 lbs package - it will cost only $114, so you save $95.90!
In reality you will save even more, because we will remove excess packaging, thus reducing the weight (don't worry about fragile items - we always use plenty of bubble wrapping!)
