Posted above, but worth saying a second time - Shimano doesn't sell direct to consumers.

If you want to buy authentic Shimano parts, you need to buy them through an authorized Shimano dealer.

In addition to the scam website(s) out there, there is a lot of fake/counterfeit/stolen Shimano stuff that gets sold through Ebay/Amazon - some of the fake stuff out there is really hard to spot and will be sold in packaging that is/looks authentic.
