DES MOINES, Iowa (AP) — Lottery officials are preparing a convenience store in rural Simpsonville, South Carolina for an onslaught of attention after revealing that the winning Mega Millions ticket worth more than $1.5 billion was sold there. State lottery officials plan a news conference at the town’s KC Mart today (Wednesday), to celebrate the lucky sale. The share of the winnings that goes to retailers in South Carolina is capped at $50,000.

The state doesn’t require lottery winners to identify themselves. For now, lottery officials are publicly urging the winner to sign the back of the ticket, put it in a safe location, seek financial or legal advice from a trusted source. They’re also urging the winner to call the Lottery. Winners have up to 180 days to come forward to claim their money.

Iowa Lottery officials say early details show that Iowa Lottery players won more than 106,000 prizes in Monday night’s world-record Mega Millions jackpot drawing and ticket sales in the game set a daily record in the lead-up to the drawing. The winning numbers in the drawing were: 5-28-62-65-70 and Mega Ball 5. The Megaplier number was 3. A total of 106,564 plays purchased by Iowa Lottery players won prizes ranging from $2 up to $1 million. Four tickets purchased in Iowa came within one number of having at least a share of the jackpot. One of those tickets won a $1 million prize by matching the first five numbers but missing the Mega Ball. The other three tickets matched four of the first five numbers and the Mega Ball to win prizes of $10,000 each.
