That sounds interesting. What are you planning to do knowing the patterns? And isn't the data private?

I am making the data available for others to use for academic analysis and/or supporting legal action. The large Canadian grocers are known to price-fix and collude, and it would be interesting to see if there are any patterns in their pricing movements. (My contribution is "getting the raw data")

The data was posted publicly online on the merchants' websites.

To confirm, it is just posted in the sense of crawling the web site, right? They don't post structured data I assume.

Correct!
