Digi-Key changed the format of their webpages, and that broke KiCost so it wouldn’t report any Digi-Key prices. If you’re getting a cost spreadsheet with blank cost information for Digi-Key with version 0.1.16, then that’s why.
I updated the KiCost web-scraper and it works now (until Digi-Key changes their format again). The working version is now 0.1.19. (I had to make a few more fixes to fix my fixes.)
One thing I’ve been thinking would be handy is if kicost had an Octopart use case where it just builds the BOM and quantities in a format that is immediately importable by Octopart. Then It could avoid all the queries all together.
