I would call and or email. Both Ken and Roman were quick to respond on emails. Roman answered the phone and Ken always had a live person answer the phone after you choose the reason for the call. I then would ask for Ken if he wasn't the one to pick up. Both were very eager to assist. With online pricing you can expect there's not a lot of room to play. And compared to my local retailer these guys were already ahead of the game (In knowledge alone).
I found Ken at stargate cinema to be very helpful. After 2 weeks of figuring out what I wanted and countless emails and calls I ordered from him. Over all his pricing was better than any other. Ken was also very good to tell me about open box deals etc and offer better pricing on those seats. His open box deals did not fit my room requirements but there was a decent savings on those.
Pricing wise Roman was a fairly close second.
There's a lot out there and much to consider. Space, comfort, quality, leather or other, and features like tables etc.
