I’m using order tags as ingredients and the price depends of the type of ingredients has, so I set the item as with no price and it can be tagged with minimum 3 and maximum 3 order tags.
Today one item was ordered with the 3 order tags and it should had the price of $3.60 but in the order line appeared with $5.60.
Only Administrator has the button change price active.
The client realized about the problem and it was fixed by voiding the item and it was ordered and that time with a correct price.
I was doing some tests and I realized that the item had a price of $2 instead of $0, plus a total of $3.6 by the order tags.
