Because I often buy index cards in tranches of 5,000 to 10,000 at a time, I’ve noticed that Oxford recently dropped their brick of 500 4×6″ index cards to $6.47, a new low for the past year when they’ve generally been hovering in the $8.50-9.50 range. As a competitive move, Amazon has dropped their competing brick to $5.82, also a new annual low. If your card index habit is price sensitive, now is the time to buy.
