Mega Millions Online Guide: Where Official Online Sales Exist
Mega Millions provides unusually clear official guidance about online sales: participating lotteries control their own purchase channels and physical-location rules.
Official online sales
The Mega Millions FAQ currently lists several US jurisdictions with online purchasing options and says physical presence within the jurisdiction is required for those purchases.
International warning
Mega Millions states that its tickets are not sold outside the United States, does not endorse companies claiming to sell its tickets worldwide, and warns that prize validity can depend on the lottery that sold the ticket.
Courier implications
That makes Mega Millions a good example of why courier users must read both the service's terms and the underlying lottery's rules.
Prize options
The official FAQ says jackpot winners can choose a cash option or an annuity, with prize-claim parameters varying by state.
