Over the years, especially since my matchbook and matchbook cover listings have become more active, there have been instances when customers don't combine or claim they can't figure out how to use the cart.
Most of the time I oblige them by manually combining items, printing the extra packing slips, copying the tracking info from the original envelope to the additional sold items and eventually refunding part of the extra postage.
However, there are cases when someone buys an item and pays for it and I pack it up within five minutes and put it on deck for the bullet train post office run. Less than ten minutes later the bell lights up again with a number indicating something may have sold and it turns out to be the same buyer. Several questions come up yet I always consider how real life retail works. People can buy something and leave the store and turn around to buy additional items. I've done this. The cashiers don't mind so when this happens on my ebay store I handle it with a smile. If the "new" sale puts the weight over the price threshold I have to get creative. Cancelling an unused label is fine but the new combined package will not make it to the bullet train nor will it be sealed for several hours just in case they want to buy a few more items spaced ten minutes apart.
