Returning an item without a receipt can be a bit more complicated, but it is still possible with Newegg. Typically, Newegg has a return policy that states that a receipt or order confirmation is the most reliable way to initiate a return. If you do not have the original receipt, Newegg may allow returns based on other forms of proof of purchase, such as an email confirmation, the order history in your Newegg account, or any other documentation that can verify the transaction.
However, do keep in mind that specific return policies may vary depending on the product type and the seller from whom you purchased the item. Some items may have restocking fees or may only be returnable if they are in unopened, like-new condition.
It is always advisable to check the return policy for the specific item you want to return. For the most accurate and updated information, you can refer to the policies stated on Newegg's website or locate the relevant contact information in case additional assistance is required.
