Father in law bought water heater 😡😡😡

Would Not Recommend

My in laws bought a water heater from Lowes. They made my 85 yr old father in law strap the water heater to the back of his truck by himself and they just watched him do it. This is not the first incident we have had with this Lowe’s on purchases. Lowe’s staff needs to do better.
