Tipster David B. sent me the photo below of Moleskines for sale at his local Costco:

These are 6-packs of 10 x 7.5″ lined cahiers in assorted colors. At $19.99 for six, it’s a pretty good deal– the full retail price is normally $19.95 for a 3-pack of this “extra-large” size, though you can also find some decent discounts on Amazon.
