Yeah, I've placed one order with Herrschnerr's and their prices were really good. Granted, a lot of what I bought was Red Heart, but come on, it was $0.97 per skein!!! I'm making afghans for the inlaws for Christmas, but didn't want to go broke doing it!!
Another good website is www.yarnbythebag.com
. It's a Canadian site, but lists its prices in USD (???). It's good if you're interested in buying a lot (think 10 skeins/balls/hanks) of the exact same yarn.
Sigh. But I still REALLY want to try Knit Picks...
