We expect you to use the API responsibly and not in a way that puts Tesco’s name,
reputation or its customers at risk. If we suspect that you have used the API in any way
that might jeopardise Tesco or its customers, we maintain the right to block your account
immediately and without notice. For instance, we are likely to block your account if you
do any of the following:

• use data sent or received from any part of the API service in any marketing or
  publicity that portrays Tesco in a negative manner;
• create an application or use data from the API that is to be used as part of a
  protest or dispute;
• use product or pricing data for the purposes of price-comparison or data
  aggregation;
• use the API in a way that causes disruption to other users of the API; or
• use the word “Tesco”, “Tesco.com” or “Tesco Labs” in the title of your
  application.
