If the site wishes to set up a discount that applies when a customer buys two or more items, which promotion would they use?

The correct choice for implementing a discount that applies when a customer purchases two or more items is the NAXML Deal. This type of promotion is specifically designed to handle conditional discounts based on the number of items bought.

NAXML Deals allow for more complex promotional structures, such as quantity-based discounts, which means that they can be programmed to trigger when the specified threshold of items is reached. For example, if a customer adds two items to their cart, the NAXML Deal can automatically apply the discount as per the set criteria.

In contrast, options like PLU Promotion, POP Discount, and Discount Denominations do not specifically cater to quantity-based discounts in the same way. PLU promotions tend to relate to price look-up codes for specific items, while POP discounts (Point of Purchase discounts) generally apply to single items or based on instant savings at the register. Discount Denominations typically refer to fixed discounts applied in specific amounts rather than volume-based promotions. Therefore, for a promotion that facilitates discounts on multiple items purchased, the NAXML Deal is the most suitable choice.
