Delorme also has Travel Bugs but you have to ask at the counter. What kind of supplies are you looking for? If you are looking for Ammo Boxes to hide a cache in, they usually have a decent selection of those at Army Barracks in Scarborough (by the Bull Moose store). For swag and trade goods you can often find it at dollar stores.... Also, I have found bulk packages of mini notebooks and pencils/pens at Big Lots.
