Ridiculously, you can adjust the amount by clicking amount of discount by taking the original price and subtracting the amount you want it to be then that difference is the amount you put in to take off!..example- you want the override to be $15.00 in the end so…
original price is $45.00 -minus $15.00 = $30. So then you push the amount button and enter $30 and then it makes it $15 in the cart!!
See why this is so freaking dumb that they removed it…in rush times it is very easy to make a mistake!!!
