Don't believe this, this is not true. May be you called too many days before the sale starts. I normally called any stores on Sloane Street or Bond Street in the middle or 3rd week of June. They, e.g. Ferragamo, BV, Prada, etc will tell me the first date of the sale and usually all the stores on these streets start their sales on the same day. Sale normally starts either on Wednesday or Thursday. You can also call Harvey Nichols and Selfridges, shops on Sloane and Bond Streets have the same sale date with these department stores. Good luck.
