There is a person on Ebay who sells Etymotics continuously. I don't know much about how Ebay works, but it's a "Dutch Auction", which means you sell multiple units and the lowest bid extends to all. Anyway, in practical terms, the bids start at 239.95 I think, and if you bid that, it appears you will get them at that.
There's something about the way Ebay functions that makes this the pro forma way to go about it. I surmise that this person is a retailer who gets a volume discount, but cannot possibly sell that many units over the counter, and so sells them on Ebay at a discounted price.
Go to Ebay and type Etymotic in the search. You'll see both ads, for the 4S and the 4P. The seller goes by the name "azvaquero" for one or the other, so you can't miss it.
Good luck, DGI
