If for any reason you're unsatisfied with an order, please reach out to the merchant directly. Each merchant will have their own policies and procedures for handling both returns and exchanges, which are typically listed on their FAQ or policy pages.
If the merchant does issue a refund, you can learn more about the refund process here.
Read their policies thoroughly. Each merchant has their own unique set of policies regarding returns and exchanges. Some will require an RMA (return merchandise authorization), have a specific location the items must be mailed to, or have fixed timelines regarding when a return must be received by. If an order or item is considered to be "final sale," it often can't be returned under any circumstances.
Get a tracking number. If you're mailing an order back to a merchant, we recommend following their return policies exactly, as well as paying for a mailing service that provides you with a tracking number. If anything goes wrong, that tracking number will often come with some level of insurance as well as the ability to prove that you did return the merchandise.
Don't "return to sender." We also advise strongly against sending an order back as "return to sender," as it may go to the wrong destination (for example, the warehouse and not the return center). This can cause the merchant to consider the return to not be valid and not issue a refund or send new merchandise. You also may not have any proof that you returned it, should the merchant say that they didn't receive the package.
