  Merchandise page redesign
  ### Is your feature request related to a problem? Please describe.
  
  The current merchandise page is a long list with lot's of text. Part of this problem is the board not hiding the merchandise items that are sold out, but I think some other layout than a list would help to improve the look.
  
  ### Describe the solution you'd like
  
  View more images side by side, and make the images larger. The text is not very important for the merch at all, so it can be pushed to the background.
  
  ### Motivation
  
  The board is getting new merch and would like the page to look better to get people interested in the merch.
  
  ### Describe alternatives you've considered
  
  Keep the page as is, because people will buy merch anyway through whatsapp promotion etc.
