Amazon has a service called: dash?relenishment?service (DRS), which literally means rapid replenishment service. An example will make it clearer. For example, if you buy a coffee machine, there is a sensor in the coffee machine that can measure the content of coffee beans and milk. When the content of coffee beans and milk is less than a threshold, it can automatically help you place a replenishment order on Amazon.
amazon?dash?replenishment?enabled? may mean that the thing you bought has this service function.
