something is wort what someone will pay. At present there is loads of cheap tat about that looks good on the net but fails quite quick. Somebody bought us a house sign it has been up 3 -4 yrs and looked ok at first, I think its only got another year in it. Change were and how you sell it not the price.
To put a cost price into it make sure you include everything including a fair amount for time. I make some great boot racks but cant get anywhere near the competitions prices, so I don't compete with them I separate myself instead. Ford and Rolls both make cars but Rolls don't give a stuff what a fiesta costs
