For every price-rule you set, you can define a priority level. 1 is the highest priority.
As rules are processed one after the other, giving them a priority order will let you choose which rule will override the others in case they apply to the same product.
Please, consider that priority both helps you manage rules that apply on the same product and refers to all rules of the same type.
First of all, the system processes Price Rules. It starts with Quantity Discount rules: if there’s a quantity rule applying to a product, all other rules (either Quantity discount or Special offer) applying on the same product will be then ignored, even if the option With other rules is enabled.
If there are, though, more than one quantity discount or special offer rules applying to different products, they will be all applied, as they do not apply to the same product and do not conflict with one another. This applies only if the option With other rules is enabled.
You can also arrange the priority by dragging and dropping the rules from the rules list:
After that, Cart discounts will be processed and will apply on the cart total. Cart discount rules can be combined and so applied one after the other.
Let’s make an example to make things easier.
- Quantity discount rule, priority 2: Product A costs $10, but it costs $5 if quantity is greater or equal to 10.
- Special offer on Product A, priority 1: buy one and get one at 50%
- Special offer on Product B, priority 1: buy one and get one at 50%
- Cart discount rule, priority 1: 20% off everything
Our cart contains
- Product A ($5 to $10): 12 items
- Product B ($18): 2 items
Price rules (Quantity discount and Special offer) will be processed first, so, No. 1, 2, 3.
Rule No. 1 and 2 apply on the same product (Product A), so, only rule No. 1 is applied as it is a Quantity discount rule and is processed first, regardless of the priority.
Product A costs $5 each.
Rule No. 2 is so ignored.
Rule No. 3 is applied on Product B. So, one is full price $18, the second one is at half price $9.
Now the cart subtotal is (12 x $5) + $18 + $9 = $87
Rule No. 4 applies on the cart subtotal, so, the final price is $69.60.
