Lupulin Exchange orders are processed instantly — payment splits, shipping purchase, label generation, and seller notification all happen within seconds of checkout. This speed is core to how we keep the platform efficient and costs low, but it also means orders cannot be modified once placed. That's why we display this reminder directly above the Pay button:
If the order hasn't already shipped, you're welcome to message the seller to request a cancellation, though keep in mind that sellers incur fees and scoring penalties when they cancel orders — so many will be unable to accommodate even if they'd like to. If you were hoping to add to the order, just place a second order.
