I checked her shop before posting and couldn't find it. I know someone out there has a source they can share. Thanks, Alex......I do *Google* on a daily basis! :)
I found quite a bit at Amazon
Donna, I got mine from http://www.zipperstop.com/
They have a wide variety of colours, the service is fast and very good and prices are acceptable. Honestly I don't know whether there's something cheaper around. Please consider that I can only choose sellers which ship abroad (I live in Italy), therefore my chose is somehow limited. The other thing I like about that website is they sell seam binding in ROLLS, I don't like to buy only a few metres (or yards!) of ribbon, I need a whole roll. I bought a white roll and then dye it the colour I want when I need it, it's very easy. If you want to know more, just yell!! ;-) Hope that was of help.
