**  To get the best value on shipping, we encourage our customers to order quantity rather than a single item. While Tshirts, scarves and most jewelry are inexpensive to ship on their own, some products are too wide to fit through a regular letter mail slot, and Canada Post charges for that. Note cards are a great add on to a larger order, but are expensive to ship as a single item.
