If you received an email receipt and you didn't purchase the item, most likely an email address was incorrectly put in during the transaction and the receipt got sent to you mistakenly. Check the last 4 digits of the credit card on the receipt (typically found near the bottom of the receipt).
If the card does not belong to you, there is no need to do anything. The receipt was mistakenly emailed to you and feel free to ignore/delete the receipt.
Note: Your information will not be recorded in our system and you should not receive more receipts like this in the future.
