Always happy to combine postage on multiple items purchased at the same time:
1-3 cars ships for the SINGLE POSTAGE RATE (within Australia and Internationally).
4 or more cars ships for a maximum of $9.70 (within Australia).
International postage for 4 or more cars is based on total weight.
Just request an invoice total at checkout if eBay doesn't calculate combined shipping costs correctly and we will adjust appropriately! Please feel free to message us if your shipping cost doesn't look right!
