body: I am about to send a package to a shop. I talked to them through Instagram and they have sent me pictures showing they are really that shop. Also my friend just visited the shop a few days ago.
  
  
  We agreed to a price and they told me the shop's address which is really the one from the shop. They also have a webpage.
  
  
  But I have no names and I am unsure what they can or have to do after they receive the package.
  
  
  Does an agreement in a chat count as a valid contract?
  
  
  What steps could I take if they don't send the money?
