Frozen Synapse Prime is not keys but steam gifts

What? You want to know how much is it worth in keys?
Use TF2Outpost and see other people's prices to get an idea.

doesn't matter what it is, the game is bundled so the cv you get is always the same.

btw, you shouldn't post here if you didn't even read the faq... and this is unrelated to your sent giveaways

The problem is not being a gift / key, but Frozen Synapse Prime was bundled at least once, this automatically makes every giveaway for it cut to 15% of it's value.

I think this game has been bundled. Any game that has history of bundle is only worth 15% regardless of how you buy it.
Edit see bundle list. Link is in faq

No, it doesn't matter if you give away key or steam gift.
Frozen Synapse Prime is a bundled game, so you will only get 15% CV.
$25 * 15% = $3.75

Games that are in the bundle list give 15% of their value.

It is bundled, it doesn't matter if it is a steam gift or a key. Bundled games are worth 15% of steam's price.
