We pushed out a huge update to the entire site earlier in the week. A lot changed in the developer portal in order to facilitate the website changes.
First, there's a price field in your game details tab that you can fill in. We use this regular retail price to calculate how much buyers are saving during the checkout process.
One of the most substantial changes is that Bonus Games can now be added as BTA content. They are separate entries in gamer's wallets and steam, desura, gog keys can now be included as well.
If you have other games in our portal, you can just checkmark the ones that you want to offer as Beat the Average bonus games.
Finally, every bonus item that you upload should now have a thumbnail image and description associated with it.
Fill out the information and upload a thumbnail so that everything displays on the new sale page and in the new checkout.
