Office Depot has a pack of 36 Staedtler Norica + 2 erasers for $6. I've never seen non-art Staedtler pencils before although I've been a long time fan of their 2mm leads, so I though I'd give it a try.
Oh my. The lead in them is amazing, especially for $0.17 each. I now understand why folks buy them online.
Anyways, that's what I've been using today
