The refund is applied to the buyer's credit card within minutes after an agent completes a refund transaction. It typically takes 3 to 5 business days for the credit to appear on the buyer's credit card statement. This depends on how long it takes the buyer's bank to process the transaction. The same is true for gift cards.
The seller (EK) holds the right to cancel the refund for returns that are not post-marked (shipped back) within the 30-day return window.
