Thank you all for coming and helping us gain some education here.
Mr. MacEwen, you mentioned in your comments to the committee, in answer to one of Mr. Lake's questions, I believe, that at times you're selling at a loss. In other words, you're selling below your cost—I think those were your actual words—which would imply that at other times you're charging a much larger margin than the average margin. Is that the case?
I come from a business background in housing, which is similar to that. There are definitely peaks and valleys. Is that how retailers get to the average?
