Free. Gratis. Literally no charge at all. We usually ship USPS so please let us know if you don't get mail delivery at your home and we will make other shipping arrangements.
Of course we hope you love your purchase unconditionally but if it's just not working for you, shoot us an email. We'll send a prepaid label and issue a full credit when your gauge makes its way back to us.
My son forgot to bring his rain gauge in over the winter and when the big freeze came, it cracked. So thanks for providing parts for your rain gauges and thanks also for the free shipping! We love our rain gauges!
