I think someone mentioned a while back about the markup on cables. The company I used to work for would throw Ethernet cables on all our data center hardware quotes for $300 a pop. Granted these quotes were usually $50k-$1M in size, so they figured the customers often wouldn't notice and they usually didn't put didn't care. But our cost on each was about $3. When a customer did notice half the time they would complain and then still just buy them from us rather than order a couple off Amazon for $10. It wasn't their personal money, so why go through the whole procurement process again on just a few cables. Total rip off. But I'd make a $10 bonus on each one I sold so I did the dirty work.
