How many campaigns, steps, and products can I have?

• Up to 25 campaigns live at once.
• Up to 20 discount steps per campaign.
• Up to 5 build-a-box sections per campaign.
• Up to 150 items in a fixed bundle's contents.

There's also an overall size limit per campaign — the editor's “Space used” meter shows how close you are. Targeting collections instead of long lists of individual variants keeps campaigns comfortably small.
