LW, you know about the special bulk flint buy being coordinated by Cains Outdoor in West VA...special sale on Tom Fuller BEFs at cost.
(I orderd 250 3/4" x 7/8"...I'll never worry about BEFs again).

Sale Ends August 15th, then he'll place the bulk order to Tom in the UK.

$39.50 for 50, and that includes packing & shipping to your house.
