If anyone is looking for a good deal on bamboo needles check out eknittingneedles.com I just ordered a set of 8-inch DP needles (5 of each) in all sizes up to 15 for $24.99 and free shipping (when you chose that option). Savings of $35.00. I have the set of 6-inch and love them. I was not a particular fan of bamboo needles before this purchase but now love them for socks and mittens.
They also have circulars for sale and accessories. Shop is located in Pennsylvania.
