Do you think $80.00 is a fair price for a 55 gallon tank?

I'm asking because:
My western painted hasn't lived in a glass tank since he outgrew the 10 gallon he lived in as a hatchling, that was 10 years ago.
I bought a new Magnum filter recently & frankly it doesn't fit very well on his 55 gallon clear plastic Christmas tree storage box so I began looking into getting a 55 gallon glass.
The local pet stores sell them for $120.00 or more, I found a deal on a brand new one for $80.00 that I can get locally.
So ya think that's a fair price? Have any of you found a tank that big for less?
Just wondering because I like to save a buck whenever I can. TIA.
