I know from experience that GST is applied and is payable once the goods arrive in the country, before they are delivered. Apart from GST, and pehaps a small customs charge, delivery was the only other major cost. Paul, is the 64 off based on the minimum order quantity for Mouser? I notice the next price break at 100 off is US$1.50 = AUD$2.73 I'm thinking about the quantity that I will want.. thanks
