I wandered into a Tueday Morning closeout store (www.tuesdaymorning.com) this weekend, and found a surprising selection of leather pen cases. All were priced at ~$5.99 to $6.99. Styles included: 2 pen ziparound, 2 pen slip cover, 4 pen ziparound with panel for 3x5 cards, 2 pen with small notepad and small sticky notes, very skinny tubular zip, and a pretty good knock-off of the Levenger pocket briefcase for 3x5 cards. I checked a another store nearby, and they had the same assortment. In both stores the pen cases were with men's wallets, socks, and accessories. These are not Coach quality by any means, but for the price, they are hard to beat.
I don't have any affiliation with them, just happy to have found bargain pen cases.
