The steam web page said that the game was 50% off, so I decided to purchased the game. I was charged full price, even though it was advertised at 50% off.
I asked them to review the matter, and they said:
Steam cannot apply sale prices to purchases made before or after sale periods.
This is true regardless of the circumstances under which a sale is missed.
Steam Support has provided you with all of the relevant information regarding this issue.
You will receive no further correspondence regarding this matter.
I don't understand why they can advertise a 50% off sale, then charge people full price. This does not seem fair. When I bought it, it was DURING the sale - not before or after.
The makers of this game should look into this, as they are being represented in a way that is not very becoming of the product.
