Yes, i do agree with Bento. Never pay any deposit unless u wan to commit. And there is some firm who wan u to pay deposit to view ur 3D. Try to find those who give free one. Like my friend case, engaged a firm to do his 4 room end up only have 3D for kitchen and only limited to change 2 times, if wan c more have to pay $50 per 3D. Alamak what is this.
