I don’t think $840 will cover installing a 40+ amp line unless you can do a lot of the work yourself.
If your local utility has a gas line at the street you’d still have to dig a trench to get from the line to your house then get it inspected - waiving sales tax wouldn’t cover that either.
We have gas, for the hot water tank, fireplace, and furnace. An electric stove came with the house. Our hot water heater is a big Tankless with a freaking electric starter, and so are the rest of the gas appliances.
