Alas, I checked at Target and although the closet products (several brands) are still available, the included END CAPS that once were 'Campy Blue' now are limited to black and white. Rubbermaid sells refills for the white caps (discontinued the blue) at ninety-nine cents for a packet of 8 - find them near the home shelving units. Ace Hardware similarly, but a tad more for the black - find them in the cork, rubber plug, and furniture coaster section. Second-hand stores for recycled closet (and shower) racks with the 'correct' blue tips, it seems.
