Steam redid their entire philosophy about sales. There used to be flash sales (the cheapest) and daily sales (second cheapest). Now it's just one sale price for the entire sale. Steam sales aren't what they used to be (by far).
That being said, the winter sale traditionally has better deals. But who knows now that the whole strategy has changed.
Still, I think the winter sale will have better deals. It's their biggest sale of the year (traditionally)
I'll wait for that sale then and just hope it's a little bit better.
