We simply can't do business without customer satisfaction. So let's just put it this way:
If you don't like what you have bought from us, just let us know by sending an email to firstname.lastname@example.org within 30 days after receiving your package.
We promise that we will make it up for you, and we will follow up with your query until you confirm to us that you are satisfied with the outcome of it. Just so you know, you will not need to send ou r ship anything back to us at your own cost.
