If you thought there were already enough discount sales on Steam, get ready for a whole lot more.Steam today announced that developers can now run their own sales via the online store, for whatever price they want, and at whatever time suits them. Previously, developers have had to work with Valve to decide on when discounts would occur. As spotted by a Reddit user , Valve announced the move in the private Steamworks Development forums. Developers can choose to create their own custom sales, or opt in to take part in upcoming weeklong sales.All Steamworks devs need do is open up the product they are aiming to discount, select however much discount they require, and choose a timeframe. Sales can last up to two weeks.Notably, the functionality doesn't appear to be fully up and running just yet, as noted by developer Dan Marshall . Check below for a screenshot of the Steamworks announcement.
