# Usage limits: redemptions, customer limits, and savings caps

> Separate code redemption limits, automatic customer usage records, maximum savings, repeat groups, gift quantities, and automatic campaign capacity.

GoGoGo Discounts provides several limits that control different things. Distinguish campaign redemptions, uses per customer, savings amounts, and offer groups per order.

## Total redemptions

**限制此折扣可使用的总次数** (Limit total uses) supports manual discount codes only. Shopify enforces it at checkout. The limit is shared by all customers and can combine with once per customer.

Automatic discounts have no equivalent strict total-use field, so this option is disabled. Use a code when limiting total redemptions; post-order counts cannot guarantee no over-redemption.

## Once per customer

| Method | Behavior and boundary |
| - | - |
| Manual discount code | Shopify limits use to once per customer account |
| Automatic discount | Requires login; records use after ordering, so near-simultaneous orders may reuse it |

This does not identify the same person across accounts or guarantee strict concurrency protection for automatic campaigns. Test first use, a second checkout after the record updates, and guest ineligibility for automatic once-per-customer campaigns.

## Maximum discount amount

Percentage rules can use **最高折扣金额（可选）** (Maximum discount amount). For merchandise of 120 at 50% off, a cap of 15 limits savings to 15. This is not a customer count or total campaign budget limit.

## Groups and gift quantity

* Bundle prices use **最多组数（可选）** for maximum groups per order.
* Buy X get Y uses **每单最多优惠组数（可选）** for repeat groups.
* Automatic gifts use **每单赠送数量** for quantity. Each rule grants one allocation per cart, not a lifetime one-gift entitlement.

## Automatic discount capacity

Current activation checks count storewide automatic discounts overlapping the campaign schedule, including Shopify admin and other apps. Activation is refused when 25 automatic discounts already overlap. Nonoverlapping future campaigns can be scheduled. Drafts and codes do not use these automatic slots.

If activation fails, inspect all store campaigns rather than only this app's list. See [campaign management](https://discount.xrtotech.com/en/settings/manage-campaigns.md).
