Maybe the reason is it’s actually a new lens being sold (under MSP) within Leica guidelines for a franchised dealer. Notice the "in-store" warranty matches the duration of Leica's warranty.
Just a guess...

I get what you are saying, but it says used... I'm just saying that I'm looking for a better deal used than that (like 75%-80% of new price like most used things sell for) and if $130 is the only difference, I'd buy new.
