“Coupons” are a bonus amount that is deposited to a user’s account that the user may receive as part of a marketing promotion undertaken by us. Like typical coupons, these may be used only for the established period of time to pay for usage fees. Coupons may be offered from time to time, in varying amounts, at the sole discretion of Storj Labs. You will be notified if you receive a Coupon. Coupons are non-refundable, and unused Coupons expire when a user closes an account or at the expiration of the Coupon.
