Once orders have been placed, we are unable to edit or cancel them. This includes editing items, quantities of items, shipping methods, and payment methods. If you accidentally entered an incorrect address at checkout, please contact our Customer Happiness Team immediately after the order is placed. If your order is placed within our business hours (weekdays from 9am-4pm PST), we may be able to make the change for you before your order is processed! We have a very small window in which we are able to edit your address, so please note, contacting us with your inquiry does not guarantee we will be able to make the change. The best course of action is always to double-check your shipping details before submitting your order! If you forgot to add a discount at checkout, please feel free to reach out to our Customer Happiness Team at info@oliveandpiper.com and we would be happy to help!
