The average price for ONE shirt when I shipped everything out last time was $9.00. I charged an additionaly $1.00 for each additional shirt. But that was a tad bit short. So I think I am going to charge $1.50 for each additional shirt. So we're looking at maybe $15.00 to most places in Europe.
I was actually shocked when I found out Austrailia was a little bit cheaper to ship. I only sent out 2 shirts to South America. That was Like $9.00 each. Japan was the most expensive if I remember correctly.
