What is the relationship between the two speakers?

W: Hello, we’re going to order 100 reams of white paper, and 300 reams of colored paper, and I wanted to inquire about your bulk rates.
M: For the white paper, we offer a 10 percent discount, so that would be $50 per ream. For the colored paper, we offer a 20 percent discount. It would be $65 per ream.
W: But I called Super Warehouse, and their prices are $40 for the white and $55 for the color.
M: Hmm, I’ll beat those prices by 5%, if you’ll order from us.
