Western Digital Store offers its Western Digital 2TB My Passport Ultra USB Type-C Portable External Hard Drive for Mac in Silver for $79.99. Plus, you get the Western Digital My Passport Denim Case with Zipper for free via coupon code "ULTRA4MAC". (You'll need to add both items to cart.) That's the best deal we could find by $20. You can also get the 4TB model with the Case for $129.99 via the same coupon. That's also a $20 low. Both deals end January 25.
