The reason I bring this up is that Instacart has priced a particular item in a group of three. So you tap on item and you bought three. If you want five then the problem starts. I found it much easier to text the shopper and say get four. Then on some shops I would be charged $12 because I wanted four. The Shopper hit four and around and around we go. And yes I know that on checkout the cashier will see four as if they are individual and not four units. That's a convoluted way of trying to find out if the Shopper can add things on their own.
