The Washington D.C. protest-themed apparel shop, The Outrage, is selling gun control merchandise ahead of the March for Our Lives Saturday.

The Outrage updated its website to feature a section labeled “Gun Control” that has items like an orange shirt that says “Walkout. Register. Organize. Lead. Enough is #Enough,” and a shirt with some of the 17 names of those killed during the shooting at Marjory Stoneman Douglas High School Feb. 14.

Buttons and sweatshirts with the words ”thoughts and prayers” crossed out and replaced with “policy change” will also be sold at The Outrage. Several lawmakers and public figures have been criticized for sending their thoughts and prayers to victims of events, like the Parkland shooting, instead of working towards implementing change.

Around 500,000 people are expected to descend on Washington, D.C. to participate in the March for Our Lives this weekend.

The store originally opened as a pop up shop in Jan. 2017 to sell merchandise to those participating in the Women’s March on Washington, but stayed open when the feminist and progressive agenda points sustained popularity following the event.

The Outrage has also sold merchandise focusing on the #MeToo movement, the Charlottesville riots, the LGBT community, and now from the MSDHS shooting.
