This is a quickie. I received a mailing that if you round up your purchase amount at participating McDonald’s restaurants, that amount will be donated to the Ronald McDonald Houses in your area.
Also, PayPal offers customers the opportunity to add $1 to their purchases to benefit DonorsChoose (https://www.donorschoose.org/donors/search.html).

Cheers!
