Refund policy
If you do not receive your purchase and have allowed 10 business days to pass, please reach out to us by email at themushieunderground.net. We also ask that you please include your name, address, purchased items and total cost of purchase, list any items that are missing or broken, if broken please supply clear pictures of the broken items that show the items damage. Emails are typically returned within 24-48 hours as we strive to meet high customer satisfaction. We will do our best to track your package and update you as quickly as possible. We do not accept returns on perishable items, those are final sale. If you are not satisfied with equipment purchased from us you may return it as long as it is still unused up to 30 days after purchase, unless a listed item specifically states it is a final sale for which no refunds will be granted. We do not pay for return labels; you are responsible for the return shipping costs and will not be reimbursed for it. You will however be given a refund for the amount paid for the equipment once we have received it, and verified it is still in working order. TMU's core foundation is built on creating a community and providing education for those who are searching for it. If there are any issues please reach out to us and we will do our best to rectify the situation!
