Amazon can be tricky since they sell their products and "front" for many smaller vendors. Direct from Amazon, probably Ok. Other vendors: I'd trust only if they were a well-known retailer. The same for other web sites. If you've done business with then for years, there's no reason you couldn't trust them for Brooks. You could always call and ask if they are an authorized Brooks dealer. Obviously a "Brooks" on ebay with a Buy it Now price for $49. delivered from Taiwan is likely a fake.
