I'm looking for any tips on where to get 12" x 18" or 18" x 12" stock the most economically.

Currently my most economical 12 x 18 paper is International Paper Accent Opaque Digital 24#/60# for $35.40 per thousand sheets.

Anyone know of any 12 x 18 paper that is even more reasonable?

I found an even better source - A J & S paper has 12 x 18 International Paper Accent Opaque Digital 60# for $15.56/ream shipped or $31.12 per thousand sheets, shipped.

I should add that I was initially hesitant to order from AJ&S because their website looks brand new and their about us page wasn't complete yet, but my first test order of 6 reams was shipped out the next day and arrived quickly.

Hmm, there should be a voting mechanism for price hunting stocks, with reviews and whatnot...

This would be a great idea - I have not seen any such animal to date for pricing even common digital / copier stocks much less less common stocks that are hard to find.

On anything but a very small scale, one issue might be negotiated pricing.

And even on a small scale of a dozen reams here and there of specialty paper, shipping costs and flexibility will make it more difficult than creating a price-matrix for other things.
