All purchases made using the BUY button are covered by Buyer Protection, so no need to worry if you haven't received your item yet.
1) If your item hasn’t arrived, contact the seller to ask for an update. Reaching out to the seller often resolves most issues.
2) Ask the seller if the item has been shipped and if they're able to provide you with more info about where your item is.
Unfortunately out-of-app payments such as bank transfers, direct PayPal payments, swaps or cash payments aren't protected. Please still report the issue so we can take action against the seller and help keep Depop safe.
Depop will investigate transactions that happened within the last 21 days. You've got 180 days from the purchase date to open a dispute within PayPal.
