What the Overlapping setting does
Every promo or deal has an Overlapping setting. It controls one thing: whether that promo can be used on an order that already has another deal's discount on it.
Find it at Management > Menu > Promos & Deals, then edit the deal.
Important: The setting that decides the outcome is the one on the promo code / cart discount, not the one on your meal deals. Marking a meal deal as Exclusive does not stop a promo code being applied on top of it. See Which deal's setting actually applies below.
The three options
Not exclusive (default)
The promo can be used on any order, including orders that already have a meal deal or another discount on them. Discounts add up.
Exclusive
The promo is refused if the basket already contains any other deal discount. The customer is told the code can't be used together with the deal in their basket.
This is all or nothing — it blocks every other deal, not a chosen few.
Master promo deal
This behaves exactly the same as Not exclusive. It stacks with everything.
Note: Despite the name, "Master promo deal" does not override or outrank anything. If you want a promo to stack, either option works and there is no difference between them. If you want a promo to be blocked by other deals, you must choose Exclusive.
Which deal's setting actually applies
This is the part that most often causes surprises.
When a customer enters a promo code on a basket that already has a meal deal in it, the system looks only at the Overlapping setting on the promo code itself:
- Promo code set to Exclusive → the code is refused.
- Promo code set to Not exclusive or Master promo deal → the code applies on top of the meal deal.
The meal deal's own Overlapping setting is not consulted for this decision. So marking "Feast for 2" as Exclusive will not prevent a £20 off code being used on it. To stop that, you have to set the £20 off code to Exclusive.
On item-based deals (meal deals, BOGOF and similar), the Exclusive setting means something different: it limits that deal to discounting one item per order. It does not block other promos.
Can I exclude just one deal?
Not at the moment. There is no way to say "this promo can be used with these deals but not that one".
Your only choices are:
- Exclusive — the promo is blocked whenever any other deal is in the basket
- Not exclusive / Master promo deal — the promo stacks with every deal
If you need a promo blocked on one particular deal only, the practical options today are:
- Set the promo to Exclusive and accept that it won't combine with any deal. This is the right choice if most orders using the code don't include a meal deal anyway.
- Reduce the promo's value so it's still viable when it does stack.
- Run the promo at a time when the deal you're worried about isn't running, using the deal's day and time settings.
If selective exclusion matters to your business, tell our support team — it's a change we'd need to build, and knowing who wants it helps us prioritise it.
Product Groups on a Cart Discount
A Cart Discount always comes off the whole basket, so it has no product list to fill in — you do not need to tick any products, and you do not need to pick a Category either. If you need a discount that only applies to certain items, use a Discount on Items deal instead.
Note: Cart discounts created before July 2026 may still have an unused product selection saved against them. Clearing it is optional and changes nothing about how the deal behaves — see Setup Promos and Deals for how to tidy it up.
Checking your settings
To see how your promos are configured at a glance:
- Go to Management > Menu > Promos & Deals.
- Look at the Overlapping column in the list.
- Anything showing Not exclusive or Master Promo deal will stack with your meal deals.
Always place a test order after changing these settings, and check the basket total before paying.
