They're not free but Boswell Pipes and Tobaccos will sell you their blends by the oz. (www.boswellpipes.com). You will have to do any ordering by phone, their number is on the site. Cornell and Diehl have sample packs available as well (www.cornellanddiehl.com), 800-433-0080. Pipeworks and Wilke is another source (www.vtpipes.com). Pipes and Cigars also sell their tobaccos by the oz. I especially recommend their Hearth and Home series by Russ Ouellette (www.pipesandcigars.com).
