Once drove to Poland from Denmark and back with a friend to buy a pair of speakers, only to realize when we arrived that they didn't live up to my expectations. Not an easy decision to make on the spot, but we still had a great trip on our ~950 miles on the road.
Some years later we drove to Brighton and back (~1,700 miles) to pick up a pair of handmade horn speakers. Those we did return with, but it was an arduous drive being we almost made it in one stretch with only a few hours sleep in the middle of the night in a van - that is, in the middle of the winter and well below the freezing point.
My current main speakers were delivered from Germany by a carrier to my front door - much easier.. 🤔
