Mylar sheets for storing Banknotes

Hey, I am looking for good (and affordable) sheets for storing my banknote collection in Toronto. Please let me know of any suggestions.. both offline and online stores are welcome.

BCW makes some pretty decent pages.  You can get them in 4, 3 and 2 pocket, depending on the size of the banknote you are looking to put in it.
Amazon has decent prices, but you may be able to find them at a hobby store as well.

BCW & many other companies make great 3 or 2 pocket pages.  

Personally, I prefer picking them up at shows or my LCS to avoid shipping costs. I have found most coins hops to sell them at good prices (eps by bulk).   If you click the OUTINGS link on the toolbar above, you'll get shops near you.  

We have covered the topic of currency sleeves here.  (Wizard online shop has a great selection & can give one an idea what to look for). Hope that helps.

Isn't there a crowd somewhere in America that makes Mylar holders?

I think they could be based in New York.

Aidan.
