Hide price with false calculation

Hello.
My name is Farook and i need some help.
i added products with price calculation:False through Automation and Action. I was wondering is there a way to hid the price? because these items may mislead the customer. or maybe not display false calculation price on recipt? is it possible.

thnx.

okay i found a way to it kind of. by making price zero in rules. but if theres a better way. plz let me know. thnx

How about Gifting the item. That way the price is removed.

Have a look here for another way to hide the price by tagging an order

Oh thanks the second way is togood. Because i can hide it on the receipt. The whole reason because though the prices arent calculated the customer might freak out and then we have to explain. No sir. Its not added tonyour total
