One thing to note about Steam is that, wishlisters will get notified of discounts if they are 20% off or greater. If you have no problems with notifying wishlisters I think it's alright. I had an issue with my game, where a lot of wishlisters didn't know the game was on sale because the sale was too low, so I set it to around 20-25% to make sure they were notified.
Just wanted to let you know if you never knew it.
