If you wish to offer a bundle price for your games, getting set up is simple. On your dashboard you will find a section for sale and bundle pricing. Here you can set your preferences for which titles are included, the sale dates, prices, etc. Under your sale options, you will find the option to set a buy all price for your titles. After selecting which games you want to bundle, you can price them both individually and as a package deal.
Projects that are in a bundle will be advertised as such on your project page for the duration of your bundle, showing users who browse your page that they can get a special on your games, and what it will include. They can view the price for the game by itself, or as a bundle.
