title: Database design for products with multiple prices
body: <p>What would be the best database design for this:</p>
  
  <p>I have a list of products and a list of clients.
  Each product has assigned 9 different prices
  Each client has assigned one of those prices for every product.</p>
  
  <p>IT would be something like this:</p>
  
  <pre>
  PRODUCTS
  id
  name
  price1
  price2
  price3
  price4
  price5
  price6
  price7
  price8
  price9
  </pre>
  
  <p>CLIENTS
  id
  name
  price_Code</p>
  
  <p>Any idea?</p>
