I found them cheapest here, they are an 'off' brand, not Bayer, but I am sure they should work, I found the link on another LC website. They are CHEAP!!

I ordered mine, they say they ship immediately , via Priority Mail, and total cost w/shipping for 100 strips is $10 even. I found the Bayer Ketostix at my drugstores locally for 50 strips, 10.79 was the lowest cost.
