Instacart question

[wurm]

I'm thinking of giving Instacart a shot. But here's the thing. Pretty much the only reason I'm considering it, is that I can't be driving all around trying to find one item I've been looking for (no, not toilet paper or hand sanitizer). So I'm creating an order of that item and several other things that we can use, just to justify the expense of using Instacart. But if they don't have the main thing I want, it's pretty much a waste of money for me to use them. The other stuff is just filler.

Is there any way of letting them know that if they don't have item X, then don't bother with the order at all?
