mmogamr$16 on Amazon for the 1941 Black Ice version. Look at the specific models and not just Zippo lighters in general as each model can have a different price.
mmogamrI'm seeing about a 3$ savings for the 1941, $2.50 for 1937, $0.50 for the Armor high polish, and $7 for Blu2 in black. The Armor high polish versino is the only one offering little savings. I'm only interested in the Blu2, so for me, it's worth it. As an Amazon Prime member, I'd generally go for the 2-day delivery over a 2 dollar savings, though.
