This makes a nice gift
Recently, our home upgraded to PEX water pipes and a new A.B.S. secondary drain system and a new water heater.  I gave the two plumbers a $100 Amazon gift card each.  They were happy and I was happy with our pipes, water heater, and secondary drain system.  Also, since I have the Amazon Chase Credit Card, I will get $10 in points!  Overall, a win win situation.
