Use the *Buy X for Total* promotion type
for products that have:

- The same retail value, for example,
*buy any 2 gifts that are priced at $5 each for only $8 (save $2)* - Different prices, for example, item A is
for $6, item B is for $5 and item C is for $5.50; and the consumer can
*buy any 2 items for $8*to save from $2 to $4

With this promotion type, you can tier
discounts, for example, *Buy 2 shirts for $20 total, or 3 shirts for $23
total.*

Note: Separate qualifying and discounted products are not
supported. Tiering is on the discounted products, not the qualifying
products.

With this promotion type, Salesforce B2C Commerce calculates the savings based on multiple products and distributes the savings evenly across all discounted products, as long as the number of products matches exactly what the rule states.

- Product discounts: price adjustments beneath product line items, representing a negative amount calculated for the specific discount.
- Order discounts: price adjustment prorated amount of the order discount for the individual product, calculated based on individual units, features and additional quantity fields.

The actual discount is the difference between the original price and the price defined by the promotion.

- For a standard fixed-price discount, the
fixed price is applied per product item.
For example, if the product unit price is $10 and the fixed-price discount amount is $8, the price adjustment is the -$2 difference between the two prices.

- If the non-discounted price of the total group of items is less than the discounted price, the price isn't raised to the discounted price.
- For a Buy X for Total fixed-price promotion, where there are multiple prices, B2C Commerce calculates the savings based on multiple products and distributes the savings evenly across all discounted products.

If you
offer the promotion: *Buy 3 shirts for $22,* and the consumer
purchases products as follows, no discount is applied because the basket
doesn't contain at least three shirts.

Shirt color | Number ordered | Unit price |
---|---|---|

Red | 1 | $13 |

Blue | 1 | $12 |

When the customer purchases products as follows, the discount applies.

Shirt color | Number ordered | Unit price |
---|---|---|

Red | 2 | $13 |

Blue | 2 | $12 |

The price adjustments are as follows:

Shirt color | Number ordered | Unit price | Adjusted price | Discount per item |
---|---|---|---|---|

Red | 2 | $13 | -$10.95 | -$5.47 |

Blue | 1 | $12 | -$5.05 | -$5.05 |

The price/discount calculation was as follows:

- Discount fixed-price: $22
- Applicable discounted products: 2 x Red Shirt, 1 x Blue Shirt
- Total price applicable discounted products: 2 x $13 + 1 x $12 = $38
- Total savings: $38 - $22 = $16
- % Savings: 16/38 = 0.421 (that is, 42.1%)
- Price adjustment per red shirt item: $13 * 0.421 = -$5.47
- Price adjustment per blue shirt item: $12 * 0.421 = -$5.05

The promotion was applied on two red shirts, but only one blue shirt, because the unit price of the red shirt is higher, and therefore the savings for the customer after the discount is higher than it would be if applied on a blue shirt.

As for any other promotion, you can specify a max-application limit to limit the number of applications of this promotion per basket.

B2C Commerce handles the tiered version of a Buy X for Total fixed-price
promotion differently from the other tiered promotion types. Usually, only
the highest applicable tier is applied. (*Buy 2 or more, get them for
$10 each.* *Buy 4 or more, get them for $9 each.*) For Buy X for
Total fixed-price promotions, all tiers might be applied, depending on the
number of items in the cart.

For example, a
merchant offers a promotion: *Buy 2 shirts for $20, 3 shirts for
$22,* with no application limit. The basket contains five discounted
products.

Shirt color | Number ordered | Unit price |
---|---|---|

Red | 3 | $14 |

Blue | 2 | $12 |

The three red shirts qualify for the threshold=3 tier. The remaining two blue shirts qualify for the threshold=2 tier. These are the applied discounts:

Shirt color | Number ordered | Promotion | List price | New price | Discount |
---|---|---|---|---|---|

Red | 3 | 3 for $22 | $42 | $22 | $20 |

Blue | 2 | 2 for $20 | $24 | $20 | $ 4 |
