For a while now aeria has a 50% bonus to AP purchases, usually for 1st time buyers.
Now they are simply putting that to a $10 package with a 50% bonus, reworded to be 500 free ap when buying $10 ap.
Its a marketing ploy. $10 packages sell easier and more often than $40 or $50 packages -w/50%bonus to both. Some would be more inclined to buy repeated $10 packes thinking its more of a deal, or w/e. All adds up the same... ='s aeria getting paid. Remember AP is not an overhead item, no production costs or wharehouse stocking , just digital representation of money, AP costs them nothing so giving away 500 ap with more $10 sales is all profit, no loss.
