Multibuy discount over several transactions - Loyalty Have not found a good solution in the loyalty system regarding the scenario: The customer comes to the store and buys the same item, and when the customer has bought X number of the item, over several transactions, the customer gets the item for free. Ex. Get the 5th Coca Cola free: 01.feb. buys 1 Coca cola, 10.feb. buys 2 Coca cola 13.feb. buys 1 Coca cola 15.feb. buys 2 Coca cola - Gets 1 Coca Cola free, and pays for 1, as the 5th is free.
