From our Terms of Service (full Terms of Service available at checkout):
"You agree to treat the Products with great care, as if it was borrowed from a family member. You are responsible for loss, destruction or damage to the Products due to theft, mysterious disappearance, fire, major stains or any other cause, other than normal wear and tear. Normal wear and tear encompasses minor stains, rips, stuck zippers or other minor damage that can be covered by the optional insurance you can pay for with your rental of the applicable Product. If you did not pay for the optional insurance and you return a Product that is damaged beyond normal wear and tear, then you agree that we shall charge you, and you shall pay, for the price for repairing or replacing the Product, as determined in our discretion, up to the Retail Value for the Product."
