Is This A Good Deal?

[Gurglar]

I found a 5 gallon glass fish tank for $20.00 at a nearby store and it comes with a corner filter, air pump, gravel, plastic plant, fish net and background.

Its only going to be for my betta but was just wondering if corner filters are good or not?

Is it a pretty good deal for whats included?

Not a bad deal to me not sure about the corner filter never used one I believe
