I have the same issue as you right now. I haven't found much information on floormall.com, or any other online dealers for that matter. What I have found is just a few negative reviews online, but the CEO of the company seems to find any and reply to them with the same message.

I did look them up on BBB and they had an A rating. They participate in BBB's conflict program I believe.

Here is a link that might be useful: http://www.complaintsboard.com/complaints/floormallcom-c48558.html

We have pretty much decided to go with them, and will report back here when we receive the shipment. Thanks for your reply.
