I want to buy a Burberry Trench coat - Page 4

Is there ever an official announcement for the in-store sale or you simply have to stumble upon it? I've heard that you can give your number to Dior and they'll call you when the sale is up but i'm not sure if that applies to Burberry as well.

I used to purchase a good amount of stuff from them when I was younger and they would always email me/send me a postcard announcing their sales. However, it's been 4-5 years since I have stepped foot in the place so I don't know what their policies are at press time.
