Slightly off-topic, but not really... This reminds me of a customer of mine who needed to rent 3 passenger vans to move 20 of his people between the airport, hotel, and office for a project in another city. It cost $10 per day to equip each van with a GPS, but he didn't know how many days he would need. Or he could just buy a GPS at Office Depot for $90, put in into the lead van, and have the other 2 vans follow. Or just buy 3 GPS's in case the vans didn't travel together. Their PHB asked me which made more sense. I told him to print google directions between the 3 locations and give them to everyone. Free. That would have required planning ahead. Instead, they bought the GPS's. I don't work there anymore.
