Regarding price, all products have a recommended retail price. This is not unusual nor is it suggestive of collusion. It is standard if you look around at other products. In fact, in the past few years, a number of brands deliberately restricted distribution of their products to protect their brand equity. This is why certain big UK brands can't be found on the sites of many retailers.
This is not something we/DS have ever sought to do. Anyone suggesting otherwise is not only incorrect but making defamatory statements based on allegations made by a select bunch of retailers guilty of selling counterfeits.
