I like the idea of making the barrier to giving as low as possible. This article almost made me give in and get a damned Prime subscription. Instead, I just keep an extra $20 bill folded up in the back of my wallet for whenever I see someone in need. By pre-designating that money, it makes it easy to give away. If I lived in a big urban area, I'd quickly be broke, but as is, it only happens now and then.

In college, I had a friend who kept fresh fruit and canned goods in his car to give away. Later when he was living without a vehicle in Baltimore, he'd usually carry a few apples or oranges to give.

It's definitely not following the philosophy of Effective Altruism, but it helps assuage my middle class white male privilege guilt.

(Edit)
I just found these on Amazon. https://www.amazon.com/Reusable-Grocery-Tote-Large-Pack/dp/B003B6478Q/ref=sr_1_17?s=kitchen&ie=UTF8&qid=1515355890&sr=1-17&keywords=shopping+bags+reusableI'm thinking about buying a set and filling them with non-perishable goods, each one a mini-survival pack with food, soap, socks, gloves, aspirin, etc. I know several SEers have spent some time on the streets. What would you most want to be handed by a random stranger? Or am I being stupid and should just stick to cold, hard cash?
