Allstitch has good prices but their shipping can be crazy if you don't meet the minimum to get it free. I buy most of my embroidery supplies from them and buy with a friend so have no troubles there. Janome needles are repackaged Organ needles so you actually are paying a much higher price just for the Janome name on the package. You can find good bulk deals for Organ needles on Amazon and Ebay too.
