You should see the deposit in just a few minutes. However, in rare cases, a refund can take up to 5 full business days.
The actual refund delivery time depends on the PayPal funding option you selected when making the transfer and on your bank's refund terms (if a bank card or account was used).
What is a business day?
Business days are the days when banks are open for work, which is typically from Monday to Friday. When making a transfer, keep in mind that Saturday, Sunday, and public holidays are not considered business days.
