One of my favorite places websites for computers/hardware is www.newegg.com and they offer many products (not everything though) that ship for free with FedEx Express Saver.
buy from either www.robotnik.comwww.mysterybyte.com or www.greenlyph.com. Robotnik ships by Canpar @ 5 bucks per shipment under 1 lbs, whereas mysterybyte ships by canadapost at 7.50 bucks per lbs. Greenlyph has a new online store and it is still under development. Currently they do not accept credit cards. All these shops are based in Halifax, Nova Scotia.
