Their marketing is completely wrong, they advertised three headboards and the price say from 799. I went to the four different store the couldn't find me, I called the customer service thats when the told me its a typing error. I am a cilent and their mistake has nothing to do with me i saw a headboard with a price saying fron 799 and I expect to get that advertised headboard with 799.
