The cost of the cases will depend on what you want. This was a custom job. The acrylic material quality are super high grade. Less glare resistance, UV protected, optically clear, slidding doors, mirror backing, and locks. I purposely chose these options so it was pretty expensive. The company I ordered from do not have online orders. They are mainly contracted with retail stores. Like I said I work for Walgreens so thats how I got them. There are private companies that you can order online but the problem with that is that 75% of the time they will be damaged in transit of delivery especially when the case is large. The best way is to look for an acrylic store around your area that does fabrication. So you can order and pick it up yourself. My cases themselves like the Autobot and deceptican cost around 750.00 each. The Macross case was a lot because it is so huge.....
hope that helps
