Are you shopping from Europe or Asia or Australia?
I know that the high cost of shipping a DVD movie across the Atlantic or Pacific oceans can be discouraging for buyers in Europe or Asia. The Post Office in Canada tells me $8. As a seller, I can not change that. None paper items (DVD movies for example) have to travel overseas and to the USA as packages not letters. That makes it more expensive. However, buyers can get more result from the money they pay on shipping.
Buy two movies at a time:
I can ship two DVD movies overseas (Europe, Asia, Australia) for $8. The weight limit for Canada Post Small Packets Air is 250 grams. A DVD movie weighs about 100 grams. The mailer to ship them weighs 20 grams. 100 + 100 + 20 =230 grams. Buy 2 and I will ship both in the same package for $8.
