Mega Millions' second-largest jackpot, $648 million, was for the December 17, 2013 drawing. Two winning tickets, one each from California and Georgia, were sold. The holder of the Georgia ticket claimed the next morning; they selected the cash option, which amounted to $173,819,742.50 before withholdings. The holder of the California ticket claimed on January 3, 2014. (The California ticket holder received an equal share, but potentially a larger cash-option amount, as California lottery winnings are exempt from state income tax)." 
In January 2012, Mega Millions' rival Powerball was altered; among the changes were a price increase of $1 for each play, as a result, a base game costs $2, or $3 with the Power Play option. At the time, there were no plans to change the price of a Mega Millions play, with or without the Megaplier (see below for the 2017 format change that includes the base price for a Mega Millions play to be raised to $2.) The price increase for playing Powerball was a major factor in Louisiana deciding to pursue joining Mega Millions, as that state's lottery joined Mega Millions on November 16, 2011.

The two different methods, both offer you, the player, the same user experience and the only difference is in the back end of how the online lottery ticket provider works. The two methods that online lottery sites use differ in one key way; They either have agents and employees all over the world that physically purchase tickets on behalf of clients or, the more recent phenomenon is when companies essentially take out an insurance policy on every ticket which is tied to the size of the jackpot. This is the difference between you playing the lottery online and betting on the lottery online*. In the latter option you are, de facto, not playing the US Powerball online but rather you are placing a bet with an insurance company on the outcome of the corresponding Powerball draw.
