Great thread idea Justin, I'm afraid I don't have any deals to share on account of being broke , however I do usually check Dickblick.com for discounts I may have to stock up on bristol. Thanks for the heads up.
For those wanting toned sketchbooks I made one myself for about $3. Buy a sheet of toned paper from an art store or paper supply store. For instance mine was 50 sheets of manila paper for $1.50 from office depot. It's pretty good quality actually and quite cheap. Then bring the paper to Kinkos or whatever you use and have them bind it. It should only be about $1-5 to bind depending on how many pieces of paper they're binding.
I got this tip from a guy at life drawing who made a dark gray one. He paid more for paper than I did. I think he said he bought the paper at Aaron Brothers.
