LAS VEGAS -- An anonymous Las Vegas casino owner has struck again - this time with a $1 million donation to help needy people.
The cards were delivered as a surprise to people the United Way and its partner programs determined needed them most.
The plastic cards become as good as cash when they're signed and can be used for anything.
It's the second time the same anonymous person has made a $1 million donation to the United Way.
The first came in December. The only difference is that this time the donor's nickname was Summer Santa instead of Secret Santa.
