I go there a lot, but mostly prevailing as there arent any other options in sec 92, 93, 82, 110... and all. They price high and have a lot of specific stuff piled up in the little area they have.
Convenience shop in the area for stationary toys etc and because he is only one he charges or rather doesn't give discount. That attitude won't last for ever as someone will open up and then customers will walk away without even telling him.
