We have definitely evolved in terms of our collection of price information. We are no longer solely collecting retail prices. In fact, since the onset of the pandemic, we are collecting online prices for most of our commodities to the extent that that's captured as part of the consumer behaviour. We know that has definitely been an impact from the pandemic, and that's the reason we are web scraping and collecting point-of-sale data. We also have delivery fees included in the CPI, so we track it in that way as well.
