If you haven’t purchased a box of letterpress Change the World cards yet (or if you’re looking to buy more!), you’re in luck. From now through August 27, get an extra 25% off all sale items when you buy a box of our Change the World cards. Use discount code zaeg6Dub at checkout to take advantage of this offer.

Our Change the World letterpress card series launched earlier this year (100% of profits are donated to critical environmental causes) and we can’t say enough good things about the organizations these cards help. Profits from the first card in the series, Sunflower, are donated to the Pesticide Action Network North America to address Colony Collapse Disorder and help save the honey bees (our food supply is dependent on them!). The cards come with organic sunflower seeds that you can plant to help the bees out!

The profits from the series’ second card, Fracking, helps Earthworks’ Oil & Gas Accountability Project change the gas and oil industry in order to protect the environment and our drinking water. The Fracking cards come with temporary tattoos — you can view photos of people wearing their tattoos (and upload a photo of your own!) on the special Tumblr page we’ve set up at gas-and-water-dont-mix.Tumblr.com.

The fine print: sale ends at 11:59pm on Monday, August 27. Order must contain a minimum of 1 box of Fracking or Sunflower cards to receive the discount.
