Hello,
I am a seller that offers combine shipping. In my case I offer combine shipping for up to 30 days. Lets say that the basic shipping cost is $6.75 I then would charge an extra 30c handling fee for each additional items. It is very important to ask for an invoice once you are done to allow the seller to adjust shipping cost. Do not pay before you get the invoice that makes the calculating more difficult and you might end up getting less.
Some sellers do not write that they offer combine shipping but if you plan to purchase more than one item from someone well you could ask if they do that. It never hurts to ask!
Hope I did not make it difficult for you to understand!
Manon
