Honestly, if it were me I would find out how much I would loose by canceling the order and determine by that if it was worth it or not. You don't say how much money you have already given them, or what the number includes. Does the 22000 also include other pieces like the Century piece? You need to go back to the contract you signed and really READ it. It sounds like you got taken pretty good, but buyers remorse won't get you out of a contract. So read your contract, find out where you stand and decide if you want to do what it takes to get out of it. Personally, it you decide it is worth it, I would just tell them your circumstances have changed and you can no longer take delivery. You are going to loose money. I would try not start a fight with them personally, because you did have a contract of some kind and finding out you didn't get a good deal doesn't change that. The sooner you get out the better, and once you take delivery there is really nothing you can do. I doubt they have much incentive to give you a bigger discount now. Once they realize you are willing to take a financial loss to get out of it, they might just to get rid of the pieces, but be ready that they will probably try to make you take delivery.
