I don't know what getting excited about office supplies says about me, but Midoco is definitely a fun place to shop for them.
Although you certainly can get by with the standard range that the big boxes offer, but having truly good tools makes work all that much better.
Some of the highlights for me include their huge selection of pens. They have a whole section of Pilot ballpoints, in various colours and point sizes. They even have disposable fountain pens, which are really neat, and, at around $4, don't break the bank. There's also a 10% discount if you buy a whole box.
Staedtler makes some of the world's best drafting supplies, and I have yet to find a better pencil than the ones they make.
The paper selection is awesome too. From math to accounting to journals, they have it all. The Swedish Whitelines notebooks and paper stand out, as do the wide selection of graphing quads.
The staff are friendly and knowledgeable, and the store is small enough that you can usually find someone. People with giant backpacks and/or no awareness of their surroundings blocking aisles can be annoying if you're trying to get to what you need in a hurry, but that really isn't Midoco's fault.
Come in here and buy something. Because life is too short for crappy pens.
