Hi Reddit,  
So here's the story: I bought something off a local version of something like Craigslist today. It was somewhat expensive, but still a very good deal compared to the price you'd have to pay for new (what it actually was I bought doesn't affect the story).  
Anyway, I go to inspect and pick up the goods and get talking with the seller. He's a good guy and we talk a bit and at some point for some reason I tell him about my daughter. He says he has a daughter too, 12 years old. He tells me a little about them and it turns out he's a single dad, raising the kid by himself after mom past away somewhat recently. I could clearly see that it still really stung.  He tells me he sees so much of his wife in his daughter and then stops talking and changes the subject. I could see the tears welling up in his eyes even though he was trying to stay tough and keep a straight face.  
After I pay him and he packs up my stuff I find out he's also recently out of a job, consequence of the economy going sour and no turn for the better in sight at the moment. Suddenly the good deal I'm getting starts to make sense. This guy needs the money to keep his family afloat... I thought about "tipping" him a bit of extra cash, but I didn't want to shame him or seem rude or condescending.  
On the way home I couldn't stop thinking about the guy though. I would really like to think of a way to make a little bit of a difference for him and his daughter. Something like an anonymous gift in the mail, something to help out a bit or just cheer up their day and put a smile on their faces. I don't know them personally, and I don't need to make this personal. I have an e-mail address and I obviously know their street address, so I can reach them either way. Anybody have any good ideas what I could send them?

<bot>: Bought something from guy, turns out to be recently widowed single dad out of a job. Want to send a gift, probably anonymous. Ideas?
