Tiers and how quantity is counted
A tier says “from this many items, take this much off”. The customer gets the highest tier their quantity has reached. Tiers don’t add up: with the default table, 3 items get 10%, not 5% plus 10%.
The global table
Tiers are set at C4D Buy More on the Tiers tab, under Default tiers. A new install starts with these:
| Minimum quantity | Discount (%) |
|---|---|
| 2 | 5 |
| 3 | 10 |
| 5 | 15 |
The rules for a row:
- Minimum quantity is a whole number, 2 or more.
- Discount (%) is between 1 and 90.
- Rows are sorted by quantity when you save. If two rows have the same quantity, the later one is kept.
- Rows that don’t meet these rules are dropped when you save.
Every product that is switched on and set to Global uses this table. Change it once and all of them follow.
A custom table for one product
Some products need their own tiers, for example a cheap consumable that can take a bigger discount at higher quantities.
- Open the product and go to the Buy More Save More tab in Product data.
- Next to Tiers, choose Custom.
- Fill in the Custom tiers table, the same way as the global one.
- Click Update.
If a product is set to Custom but has no valid rows, it uses the global table instead. Choose Global again at any time and the custom rows are kept but not used.
How quantity is counted
Quantity is counted per product, in the cart.
- Three of the same product count as 3, and that product’s 3-item tier applies.
- For a variable product, all variations are added together. One small and two large count as 3. Each variation is then discounted from its own price.
- Different products are not added together. Two T-shirts and one mug don’t make 3 items. (Pro rules can pool them, see Pro.)
When a tier is reached, it applies to every unit of that product in the cart, not only the extra ones. If the 3-item tier gives 10%, all 3 items get 10% off.
Items that are part of a C4D Product Bundle are left out, so the two plugins don’t discount the same item twice.
Sale items
By default the discount is taken from the price the customer would pay now, so a product on sale is discounted from its sale price.
To leave sale items out, go to C4D Buy More › Advanced, tick Do not discount products that are already on sale next to Sale items, and click Save settings.
Coupons
By default the tier discount and a coupon can be used together. To stop that, untick Allow the tier discount together with coupons next to Coupons on the Advanced tab. The tier discount is then removed from the cart while a coupon is applied.
Rounding
The discounted price of one item is worked out first, then rounded to the number of decimals your shop uses for prices (WooCommerce › Settings › General, Currency options). The line total is that price times the quantity. A 10% discount on 9.99 gives 8.99, so three items cost 26.97.
A product with a price of 0 is never discounted, and the discount never makes a price go up.
Where the discount shows on an order
Each discounted order item has a “Buy More Save More” line with the percent that was applied, for example “10%”. You see it on the order screen in your dashboard.
