If there is a Container Store near you, check out the office section. Two Container Stores in the Dallas are both sell an assortment of Rhodia and Clairefontaine pads, notebooks, and paper, as well as Xonex notebooks, which look good, but I cannot vouch for the FP friendliness. Also they have Amodex 1 oz containers for $6.99.

Prices I noted are as follows:
Sm Rhodia notebook $3.49
Block #8 notebook $3.49
Small notepad $2.99 (3 3/8 X 4 3/4 size)
Lg notepad $3.99 (4 3/8 X 6 3/8 size)

Xonex A6 journal is $4.99, don't know how many pages

Clairefontaine notebook 6 3/4 X 8 3/8 is $8.99,
notebook 8 1/2 X 11 is $16.99

They had the 1 oz nalgene screw top bottles in the travel section for $0.59 each, so I bought 6 to store and mix ink. They also have 2 oz and 4 oz bottles, narrow or wide mouth. I got the wide mouth, even though my Danitrio Classic fit handily into the narrow mouth. No additional cost, and easier to get the ink in.
