I'm in Falkirk, 18 mile away I've no transport the now but if your seller could get to Cumbernauld train station
I'd nip through and meet them,it's only 30 mins away.
Got a couple of boxes from Thomann here and some of those wee air bags so packing material not a problem.
The folks are retired so it could get picked up by a courier from there.
Any good to you?
