What are the speakers mainly discussing?

W1: I hear that the annual cookie campaign held by Devon Bakery was a huge success this year. The owners were able to raise $1, 560. Did you buy any cookies?
W2: Oh, my, I forgot all about it, and I really would’ve liked to have supported the campaign. When was it?
M: It was during the last week of September. The cookies were sold at half price, and all proceeds were donated to a nonprofit organization that provides aid to the homeless.
W1: What a lovely gesture. I’m so glad they made a lot of money.
W2: Me, too, but I wish I had taken the opportunity to help their cause.
M: It’s not too late. I’m sure you could still make a donation directly to the organization.
