The pulls in the photo say 'YKK' on them. Exactly what I was thinking... way too expensive. I was excited to see zippers, but then realized there were only 12. You can get 100 of the 24" long pull zippers for $115 from ZipIt, so $1.15 each. At the $46 drop price, that is $3.83 per zipper. Even in their smallest bundle, ZipIt sells these for $1.45 each.... Even if the drop goes to the lowest price, that is less than half the drop price.
Edited because I originally said, "For $45 you get 50 of them from ZipIt." and then realized that was for 12" zippers.
