Thanks Dan: I offer something like a $7.50 saving for no jewel case but so far, no takers and the overseas shipping for Cds with the jewel case comes to around $7.50 Canadian funds.
So I'm thinking about sending them with jewel cases but in regular envelopes for overseas, just to keep the weight under 100 grams.
Canada Post adjusted their prices a few years ago, specifically to target CD sales and I'd like to find a way to beat their pricing and still please the customers.
