I have placed many orders through Niagara. They have lots of stuff that other online retailers don't have. I once placed an order for an item that went out of stock before they were able to ship the product. They kept the order open for 60 days and cancelled the order when they didn't get new stock in that time. I don't consider that to be Niagara's problem. Your case is even less Niagara's fault IMO. You're trying to source a part that you know is discontinued. Good luck. I hope you get it, but I wouldn't be surprised if you don't.
