Thanks Favorite Fabrics for the info. Everything you have said makes complete sense, but still some of the shipments I have received don't seem to have followed these guidelines (orders for $50-$100 sent Canada post with no additonal fees, and orders in this same range or slightly higher and I was charged additonal fees). I have just been keeping track of which orders due incur the additional fees and take this into consideration when determining final price per yard or meter. As you say I am more apt to order from the suppliers that are able to ship orders in such a way that these additonal fees are not required and therefore not part of my final cost. I also pay close attention to what companies are charging for shipping as some are using "flat rate" and I pay approx. $12 to receive 6-7 yds of fabric and others have rates well over $20 to ship the same amount of product (I bet you can guess who gets my order).
