I don't think Surefire lets their retailers go below a certain price on most of their products. Case in point, LA Police Gear is selling the Surefire E1B Backup LED Dual Output Flashlight in silver for the standard price of $140. However, they are throwing in FIFTY (50) free batteries.
Note: for comparison purposes, they sell Surefire batteries at six for $15, twelve for $21, and 72 for $126. Even at the best rate, 50 batteries is the equivalent of $87.50.
Note II: Anybody need any batteries cheap? I'm going to have some extras.
