I was thinking about Amazon affiliate referrals for charity just the other days after a friend posted his charity's Amazon Smile referral link. Of course the Smile payout is a fraction of what the affiliate percentage pays. I was thinking about just having a page of with maybe the current top 50 items (five rows of ten) for the week in Amazon's sales rank - as cards with thumbnail and name/price/rating. Then I'd rotate through charities each week based on visitor input, verify the week's haul for them and cut a check to the charity. An alternative to the top 50 items would be to incorporate items related to LifeHacker's "best times to buy" lists. I figured I should just double check the TOS first and haven't had the chance. It's interesting to see others thinking about this.
