Slightly Stoopid are offering a 4/20 discount for their show coming up on June 22nd at Big Sky Brewing. Today (April 20) only, you can get tickets for $24.20. The offer is only available online, so all you have to do is choose the $19.22 ticket price, and after fees your total will be $24.20.

Sorry about all of that math, I realize it is not the best day to present complex equations. This offer ends at midnight so don't space it out.
