At Deal Yoga, we do our best to ensure that all products are tested and in working condition. Most of our products are new in box unless otherwise stated in the description. All sales are final and returns or customer disputes are handled on a case by case basis. For every customer dispute, you must present a valid proof of purchase including a receipt issued by Deal Yoga with your name on it and have a valid form of identification that is not expired to present. It is important to also understand that because Deal Yoga offers liquidated and surplus items, we do not offer any guarantee on product quality, return of investment of individual sales online and in person, and does not guarantee any level of quality of the products and services at this time. Deal Yoga works with customers on a case by case basis to offer superior customer service and experience but Deal Yoga does not guarantee anything at this time with it's products, shipping, and services.
