+### Promotion Limits
+
+In the summary section of the promotion's details page, you can see the usage limit of the promotion, if set during its creation. This is the maximum number of times the promotion can be used across all orders.
+
+A promotion's usage can also be limited by:
+
+1. The campaign's usage limit, if the promotion is part of a campaign. This is the maximum number of times all promotions in the campaign can be used across all orders. You can set this limit when [creating the campaign](../campaigns/page.mdx).
+2. The per-customer usage limit, if the promotion is part of a campaign. This is the maximum number of times a single customer can use promotions in a campaign across all their orders. You can set this limit when [creating the campaign](../campaigns/page.mdx).
+
+Once any of the promotion's limits are reached, the promotion can't be used anymore. For example, if a promotion has a usage limit of 10 and is part of a campaign with a usage limit of 50, the promotion can only be used 10 times even if the campaign's limit hasn't been reached yet.
