On average, neon signs cost anywhere from $400 to $1000. Our signs are as affordable as can be, but sign costs will vary considerable depending on quantity: Are you after a one off or is it going to be mass produced for a retail chain? It will also depend on the style desired – Flex neon is much more affordable than 180 and 360 led neon signs, which are a lot more complex to be produced. It is certainly cheaper to produce vs traditional neon signage. It is also way safer to handle and much more energy efficient.
