I have a new puppy, and was impressed with Pet Smart. I thought it was particularly interesting that they asked if I wanted to give an extra $1 for the Humane Society.  I bet they have high conversions on that – a $1 contribution won’t break the bank, and the cumulative impact can be huge.

McDonald’s has for years had a coin collector for the Ronald McDonald House, but why don’t more retail companies offer the opportunity for micro-giving at the point of sale via automatic charge? Stores could even give you a menu of say 5 charities from which you choose. This could also work well for online retailers.
