The Steam Controller is on sale for 90% off as part of Steam’s Autumn Sale. If you were looking to pick one up but for some reason still haven’t done so, you’ll want to take advantage of this sale. The Steam Controller is going away.
Presently priced at $5 plus shipping (your mileage may vary), Valve has confirmed that this batch of controllers will be the last. After that? You’ll need to go to the second hand market. The store page also notes that due to high demand, shipping may be delayed. The controller should ship and arrive within 4-8 days once the order is processed.
