Collection bonus offers apply to all items within the collection and can be either a fixed point amount per product or a multiplier.
Fixed point bonus will add the the bonus to the total for each quantity of an item in the cart. For example if a customer buys 3 items in a collection with a 100 point bonus, they will receive 300 bonus points in addition to their regular rewards.
Multiplier bonuses increase the rewards value of each items in a collection. These also apply to each quantity of an item in the cart. The reward value of an items purchase with a multiplier bonus off is calculated as Quantity Purchased × Purchase Price × Point Award Value × Multiplier.
For example if a 2x multiplier is offered on an item sold for $50 with loyalty awards equal to 5 points per dollar, and the customer buys 3 of them, they will receive 3 × 50 × 5 × 2 = 1500 reward points.
Bonus offers can be optionally configured with a start and end date. If no start date is entered then the bonus offer begins immediately. If no end date is entered then the bonus offer does not expire.
