Hmm that's a good point.. I never thought to buy them in bulk... I'll try to shop around and see what deals I can get. I had looked on the Grace company site for feedback on the sharpener but the comments are odd.. most of them were comments on having luck ordering from the company or how it was shipped but none really comment or critique the product at all.. which makes me think that maybe there are not that many good reviews on the product's performance or quality.
Thank you for your reply!
