A good idea when buying on line

A guy about 2.5 hours from me was selling Sonus Faber Concertos on Craigslist for $1000.00 including the stands, factory boxes and manual.  I considered driving to him and even taking a receiver to test the speakers. Then I had an  idea. I suggested he bring them to my house so I could listen to them on my system. If I wanted them I would give him $1200 ($200 more than he was asking).  If I didn't want them, I'd give him $200 for making the trip.  He agreed. They looked and sounded great and I bought them.  I thought the extra $200 was well worth the guarantee of eliminating any problems and not being disappointed.  Although, maybe I should have suggested $100!
