Quick answer: To prevent discount stacking in WooCommerce, define rule priority in PricePress, choose the application mode, use Individual Use Only where appropriate, and set a separate policy for standard coupons.
To prevent discount stacking in WooCommerce, you need an explicit policy for overlapping product offers, cart discounts, and coupons. Disabling one coupon is not enough if two automatic pricing rules can still apply to the same item.
PricePress’s feature description includes rule application modes, priority, Individual Use Only, coupon suppression, and usage limits. These controls serve different purposes, so configure them around the actual offer you want customers to receive.
1. List the promotions that can meet in one cart
Imagine a $100 product eligible for a 20% clearance discount and a 10% customer discount. If the reductions apply sequentially, the price becomes $72: first $80, then another 10% off $80. That is a 28% effective reduction, rather than a simple 30% sum.
The result depends on the calculation base and rule behavior. Include standard coupons, existing sale prices, bundles, and shipping rewards in your review.
2. Choose the rule application mode
PricePress describes First Matched Rule and Stacking All Matched Rules. First Matched Rule suits a policy where priority selects the applicable offer. Stacking suits campaigns where combining rewards is deliberate.
Do not assume First Matched Rule automatically finds the mathematically largest discount. Configure priority so the intended promotion is encountered first, then verify the result with an overlapping cart.
3. Use Individual Use Only where exclusivity matters
The supplied description explains that Individual Use Only locks qualifying products against lower-priority rules after the exclusive rule applies. Use this for a promotion that should not receive additional product-level reductions.
For example, place a clearance rule at the intended priority and make it exclusive if your policy says clearance items should receive that offer alone. Then test whether unrelated items can still receive their own valid promotions.
A product lock should not be treated as proof that every cart-level reward or shipping incentive is blocked. Verify those combinations separately.
4. Set the WooCommerce coupon policy
Choose whether ordinary coupons may combine with your dynamic campaign. If coupons are suppressed, explain the promotion terms before shoppers spend time entering a code.
PricePress also describes coupon-gated rules, where a specific coupon is required to unlock an offer. A required-code condition and coupon suppression need to be tested together if your campaign uses both; avoid a configuration that prevents the intended qualifying code from working.
5. Add redemption caps for budget control
A global campaign cap limits total redemptions. A per-user cap limits an account’s redemptions. Neither replaces stacking controls: a promotion can be exclusive and still cost too much if its value or audience is poorly chosen.
Likewise, a per-account limit does not prove one redemption per real person. Describe it accurately in your offer terms.
6. Test an overlap matrix
Create carts covering each offer alone, two offers together, a sale-priced item, a coupon, and an ineligible product. Record expected unit prices, product subtotals, and the checkout total. Resolve differences before activating the campaign broadly.

Frequently asked questions
Does First Matched Rule automatically choose the biggest saving?
Do not assume that. Set priority to produce the intended match and test a product eligible for more than one rule.
Are two successive discounts the same as adding their percentages?
No. Applying 20% and then 10% to a $100 price produces $72, a 28% effective reduction, when the second discount uses the already-discounted amount.
