I bought a "disposable" glass peppercorn grinder with peppercorns at Wal-Mart for $3-$4, and bought a mixture of different peppercorns also at Wal-Mart for the same price. When the grinder was empty, I used a tongue and groove pliers to remove the grinder cap to refill. I have a few of these grinders to use for other seeds such as fennel to use for recipes.
