Dave,
Given that your prepared to make a 300 mile round trip to deliver it, can I make a proposition?
I'll buy the guitar, and come and pick it up. At a conservative estimate, your travelling expenses will be 25p a mile. OK?
Guess what! £0.25 x 300 miles =£75!!
So, if I pick it up, I get the guitar for free?!?
*grin*
