Mr. Chair, thanks for the question.
There absolutely are, and that's part of establishing the framework that we need to have in place. We need to look at the grouping of the various commodities to assess the scope for the discounting associated with bulk buys. That's one factor through which we very much have realized savings.
This is part of deciding. Not all of those commodities, however, benefit from bulk buys. The balance, I think, will be the bulk buy versus the efficiency that may come to a particular department from the timeliness of getting a set of goods and services.
We will have to go through these, commodity grouping by commodity grouping, to do the assessment. It won't be the same for every single department that takes services; it will be different. That's why I'm talking about the need for that consultation.
