Email: Search your email inbox for the purchase confirmation or sales receipt. Look for emails from the retailer or online platform where you made the purchase. The receipt is often sent immediately after the transaction.

Online Account: If you created an account with the retailer or online platform, log in to your account and navigate to the order history or purchase history section. There, you should find a record of your purchase along with the corresponding sales receipt.

Retailer's Website/App: Visit the website or mobile app of the retailer where you made the purchase. Look for options like "My Account," "Order History," or "Purchase History." The sales receipt should be available for viewing or downloading from there.

Review Return Policy: Familiarize yourself with the retailer's return policy. This information is often available on their website or provided in the purchase confirmation email. Pay attention to important details such as the time frame for returns, condition of the item, and any specific requirements.

Contact Customer Support: Reach out to the retailer's customer support to initiate the return process. You can usually find their contact information on their website or in the purchase confirmation email. Provide them with relevant details such as your order number, item details, and reason for the return.

Follow Return Instructions: The customer support representative will guide you through the return process. They may provide you with a return shipping label or instructions on how to return the item. If it's an online purchase, they might ask you to print the return label and affix it to the package.
