$2.4 is the price per 50 levels in the range of levels 300 to 400, if you want to order more than 50 levels, then order multiples.

Process
1). I will log in to the player account
2). Players must wait for the process (duration depends on the number of levels ordered and player account specifications)
3). During the process you are not allowed to crash/log in first
4). I will confirm via chat when it's finished
