0P GAs and CV

If the drop the price, yes your CV will go down. It's unfortunate but it's too hard to track prices history and that sort of thing.

When you create a giveaway, you get full, reduced, or no CV based on the date you created the giveaway. This will not change, you will always keep full, reduced, or no CV, but your CV will slowly drop over time because it is calculated based on the current US full retail price. Steamgifts does not remember the price of the game on the date you created the giveaway. Temporary sales do not affect your CV.

Example:

• You create a giveaway for a $60 full value game and get $60 CV.
• Some time later, the game gets bundled or sold at a discount of around 95% off or more.
• Everyone who now creates a giveaway after that sale started gets 15% CV of the $60 game. You will continue to get $60 CV while all the new giveaway creators will get $9.
• Then at a later date Steam keys for the game are given away in a free promotion.
• Now anyone who creates a giveaway gets 0 CV. People who gave it away after the sale still get their reduced $9 CV, and everyone who created a giveaway before the sale still gets the full $60 CV.
• Then the full price of the game permanently drops on Steam to $40.
• You now get $40 CV and everyone who gets the reduced 15% CV now gets $6.

Edit: I should also add that support will backdate the full, reduced, and no CV dates based on when the game was in a bundle or free. If there is a bundle today that should cause the games to drop to the reduced CV category, but you create giveaways for the games before support has a chance to drop the games down from full CV, you will temporarily get full CV. Then when support adds those games to the reduced CV list, they will use the date of when the bundle was released so that anyone that created a giveaway from the day the bundle was available will have their CV dropped down to the correct reduced CV for those giveaways. The same applies to games that are given away in free promotions.
