deposits

I'm sorry to say this, but they did not rip you off. You ASSUMED what the amount would be without asking the question. You can never assume anything. It is your responsibility to make sure you understand the policies before you sign on the dotted line. If you don't like a companies policies after you have read their practices on returns and restocking fees - walk away. This is what I tell all my customers when hired to pick out furniture for their homes.
P.S. I do not and have never worked for this company.
