I was the one who mentioned the UE 900. My friend works for one of the electronic shops in Toronto. He mentioned to me that he knows the owner was in touch with Logitech regarding the UE 900 and some other models. He said that his boss was offered a limited quantity by Logitech and they tried to negotiate it. At this point NCIX already listed the UE 900 for $199.99. The feeling was that something is going on with UE as in Australia and in the UK they were discounted and no longer available on the Logitech website. I checked it out and it was true. He also mentioned to me that Amazon USA is low on stock and they don't know what's up with that. It seems like Logitech had some stock to clear and they were looking to unload it to the highest bidder. At this point I asked him if it's worth buying and he said, "buy, don't open it and return if the price comes down". I posted that there is a rumour that the price might go to $109 based on what I was told. I emphasized that it's a rumour from my friend, so people should take it with a grain of salt. Sure enough, a few hours later NCIX came with the second Logitech deal; $190 shipping directly from Logitech, no returns, exchange only or replacement. I guess this the stock that my friend was talking about, I am just guessing as no one really knows. When I called him yesterday he assumed that Logitech had a small stock of 50+ pieces roughly and since Amazon US is pretty dry it seems like they didn't want to let buyers sell it less than the already good price that was offered by NCIX.

I hope this clarifies what went down. 1 head-fi member PM'ed me and asked me about that, I suggested him what I was told: you can order and always return if unopened, but mind you there will be shipping cost to and from and also maybe duty and sales tax.... So at the end of the day, your money, your call.
