Odd donation tactics for Colo Spgs Firefighters fundraiser drive

[Little Dutch]

I received a call from someone soliciting for a Colorado Springs Firefighters fundraiser a minute ago. I thought the interaction was weird, so I'm sharing.

It went about like this.
<random softphone number ringing on my phone>
Me: Hello, This is <Dutch>
Lady: <Opening spiel stuff> If we send you an email or an envelope, would you donate to the Colorado Springs Firefighter fundraiser. The information about the fundraiser will be included so you can research and verify the org... etc. <more opening spiel stuff>.
Me: Send me an email. <I don't mind donating to the firefighters, although we usually do our donations once a year>
Lady: Before I can send you an email I need to know much you will be donating.
Me: I don't know, I haven't received the packet telling me what the donation is for.
Lady: Can we count on you for at least $25?
Me: I do not know, I have not yet received the packet telling me what the donation is for.
Lady: Thank you, have a good day.

And she disconnected.

She never did get my email, so it's likely a legit drive. I don't mind donating, but I like to know for what I'm donating before agreeing to anything. At least when the arthritis foundation, Mormons or Jehovah's, etc call me they have a website they can give me.
