Pokemon Go Niantic is Charging Some Players More for the Same Thing

Niantic and Pokemon Go are charging some users more for the same thing, and players are not happy about it.
Pokemon Go players noticed a huge price difference in the new Lure Module Box. It seems like Niantic charged some players more for the Lure Module Box, while some players got the same box and contents for half of the price.
Every Pokemon Go player is getting a different price for the Lure Module Box. Some players pay 700 PokeCoins, while some pay 350 PokeCoins for the same box and same contents.
One Pokemon Go player noticed the price difference and contacted Niantic/Pokemon Go support on Twitter. Here is their response.
Thank you for writing in with your concern, Gary! As we test out new features and ways to improve gameplay, some players may have slightly varied experiences. You can find out more information about why here: https://t.co/gJ37Wt0nLb We appreciate your patience. ^ST
