I haven't seen Shelley around lately, but she's the Ribbon Heaven expert! Here's a thread all about Ribbon Heaven. It's a little old now, so the prices listed may not be accurate, but it should answer a ton of questions for you. http://hipgirlclips.com/forums/group...bbon-buys.html
And as far as out of stock ribbon goes, I've been told when the site says they're out of stock, it's usually wrong. I've never had a problem with ribbon being out of stock, but if you find something you want that's not available, you just need to email Donna & she will update the site if she has more.
Hope that helps!
