I just used this code: QWV35 for a one-year ads free subscription to a great weather site, Wundergound. Worked for me. You can also, in settings, send a free gift to someone via email for a 1-year membership after you sign-up. If you wish to purchase a year's access it's only $10, not a wallet-breaker and worthy of an excellent site.
