>to you it seems like your data but to Walgreens they see it as theirs the value of this data comes from what did I buy, what else do I buy, where am I, who I am, etc. to your point, Walgreens does not sell to their competitor CVS data about what they sell, when, and where. so if that really is their argument, it's refutable.
