Does Three sell refurbished phones?

Tips for using a Three voucher code
Three sells mostly on plans and contracts, so a voucher code is not always accepted. If the checkout shows a promo code field, enter your code there before you confirm the order, then check the monthly and upfront prices in the summary. Read the code's terms, as it may only apply to certain plans or devices.
