I clicked on the supplied link and the flares are just over $540. I assume "plus shipping". Getting them from O.P. at $520 including shipping is a no-brainer.
If only I needed them...
That is correct, common sense has left the building!
It's about $700.00 shipped new from Xenon as I did the calculations on their website. Which I can imagine they do have accounts with shippers and therefore have much better rates than little 'ol me in CA, Bahaha...
Using my Jedi mind trick/spell or whatever you want to call it...
YOU NEED THEM, use the force Luke!
