Just want to say, this may just be an assumption. Just because Tesco lists all the promotions at the bottom of the receipt, it’s just for presentation sake - it looks nice to show the customer all the savings in one place then a savings total. I also like this approach. There is nothing to say you can’t do that in SambaPOS on the receipt (yes I know this is not related to your calculation question), just hide the Promotion order tag group on order lines and then at the end, you can use {ORDER TAG DETAILS:X} to display the total for each promotion then {ORDER TAG TOTAL:X} to display the total of all promotions (total saved).
