(KTVI) - Tuesday is Earth Day and the Cardinals are teaming up with Mers Goodwill to help the environment.
Here is how it works -- from 7 a.m. to 6 p.m. tonight, anyone who drops off used electronics receives a voucher for half priced Cardinals tickets. You can drop off computers, printers, cells phones, clocks and other electronics.
In exchange, you'll get to see the Red Birds in action. The team says the event has a positive impact on the environment and economy.
All of the items will be recycled. The event is happened on 8th Street near Busch Stadium, just south of Interstate 64/40.
