HASLAB Tiers are levels of upgrades that are unlocked when certain campaign goals are reached, such as achieving a set number of backers. The goals and upgrades may vary by project and details are provided on the campaign product page, or revealed throughout the Project Backing Period. Please note that meeting or exceeding campaign goals is not a guarantee that additional Tiers will be added.
Early Bird Specials are added as upgrades if certain campaign goals are met early in the sign-up period. The upgrades and deadlines will vary by project. Unlike Tiered upgrades, which can be unlocked at any point during the Project Backing Period, Early Bird Specials have a deadline and may come with additional limitations that are detailed on the campaign product page.
