If I may join the party...
I usually give away my unused stuff but since this is a bit bigger, let's give it a try:
I have a safety box, a medium size one, practically new -little use, never been broken.
I need a piece of luggage. I trade my safe box for one. Old fashioned yes, but NO 360 degrees wheelie kind of thinghie wanted. Backpackers stuff also an option.
Or a used bike. Irishtu, can I interest you in a safety box?
