Review of Techni Photo

I am not happy when parents from other international schools telling me that Techni Photo is charging them $50 less for a same set of basic photo package. Our children go to different international schools but what we had ordered were basically the same thing. My friends' children are going to the ESF schools. Whereas my children are attending FIS on the island. Does it mean that people are suppose to pay more just beause they think people do not really mind paying more? For a lot of things I know it costs more on the island but I cannot believe even the Techni Photo company is trying to rip off parents with that!!!
