The term “deal in” includes making, taking, buying, selling, redeeming, or collecting.
(2) The term “lottery” includes any arrangement, other than a savings promotion raffle, whereby three or more persons (the “participants”) advance money or credit to another in exchange for the possibility or expectation that one or more but not all of the participants (the “winners”) will receive by reason of their advances more than the amounts they have advanced, the identity of the winners being determined by any means which includes—
The term “savings promotion raffle” means a contest in which the sole consideration required for a chance of winning designated prizes is obtained by the deposit of a specified amount of money in a savings account or other savings program, where each ticket or entry has an equal chance of being drawn, such contest being subject to regulations that may from time to time be promulgated by the appropriate prudential regulator (as defined in section 5481 of this title).

Subsec. (c)(4). Pub. L. 113–251, § 3(a)(2), added par. (4).
“Congress finds that—
the annual savings rate in the United States was 4.1 percent in 2012;
more than 40 percent of American households lack the savings to cover basic expenses for 3 months, if an unexpected event leads to a loss of stable income;
personal savings provide Americans with the financial resources to meet future needs, including higher education and homeownership, while also providing a safety net to weather unexpected financial shocks;
in the States of Michigan and Nebraska, more than 42,000 individuals have opened prize-linked savings accounts and saved more than $72,000,000;
prize-linked savings products have been shown to successfully attract non-savers, the asset poor, and low-to-moderate income groups, providing individuals with a new tool to build personal savings; and
encouraging personal savings is in the national interest of the United States.”
 So in original. The word “or” probably should appear.
