Paper Cost

I'm envisioning our invitations as beautiful pieces of work (created by someone fantastic!) once they are done. Miss Eggplants' invitation below via weddingbee is where my inspiration for the layout/assembly comes from:

The contents of our invitations will include:

- A black 5x7 pocketfold

- Plum ribbon with monogram seal attached on the outside of pocketfold

- Raspberry backing cardstock

- White cardstock with black printing

- One white outside envelope

- An RSVP postcard or RSVP card and return envelope

- Inserts with info about the reception, directions, etc.

I sat down tonight to find out what the raw materials for the invitations are going to cost me. I compared three on-line paper companies to see what I can get for the best price. Here is the breakdown for 125 invitations:

(Breakdown does not include price of ribbon, postage, or cost of printing.)

I highlighted the cheapest of the three companies for each component. The only problem with Paper Source is that the company doesn't carry anything in a deep plum or raspberry.

Are there any other affordable paper companies out there that I missed!?
