Panasonic 7-14mm for m4/3

I am selling a 7-14mm f/4.0 lens for m4/3. The lens has some scuffing and scratches on the barrel but is optically perfect. However, I absolutely do not understand how to integrate UWA into my photography and it's certainly not worth the price of entry.

I am willing to let it go for $720 shipped, but I am only able to accept payment via Amazon Payments. No Paypal.
