Another thought I had was how it will handle multiple people filling the same "cart". Often I'm shopping with my girlfriend and, being the time-strapped millennials that we are, we'll split up the grocery list to divide and conquer and meet back up at the checkout aisle. How does this reconcile that? Would both of us have to scan in when we enter the store, or link our accounts in some fashion?
