Dealing with double batches on Instacart gets much easier once you apply the tactics to separate the items from two orders. First off, you can place a carrying basket into the cart and place everything from order A in it, and the items from order B in the cart. Also, you can move through the store by sections, placing each item in the basket or the cart accordingly. This way, you won’t have to revisit the sections you’ve already been to again.
