I make giveaways but i dont get my contribution points?

The games you giveaway are from a bundle. I think bundled games only give you $30 contributor points maximum

These games have been in a bundle and special rules apply to their contributor value.

The first 25$ of bundle games are counted as non-bundle. Value above that is only added to a maximum of 20% of your non-bundle contribution.
That means you can only reach a contribution of 30$ with bundle games alone (25$ + (20%*25$)).

Formula:

adjustedbundlevalue = bundlevalue - Min( bundlevalue , 25$ )
adjustednonbundlevalue = nonbundlevalue + Min( bundlevalue , 25$ )

contribution = adjustednonbundlevalue + Min( adjustedbundlevalue , adjustednonbundlevalue * 20% )

Giveaway for the joy of giving, not just so you can enter a few more giveaways. I know I won't gain squat from 7 of my current giveaways, but they are great games that I want people to play.
