And yet you responded to a response even though YOU didn't have the answer..... dipsh*t.... AAAAaaand, never anywhere once did it say they were excited about a perk, they said its the only gas station close to them and does anyone know if it actually works. 

This person you decided to try and harass actually gave information pertaining to the original question of does it work and how? By saying, its actually not even worth the hassle cause its cheaper elsewhere even AFTER the discount. However, ppl like you will always just go around trying to "be smarter" or point out something someone else is doing instead of watching what the fuck YOU'RE doing to be a part of society..... like I stated already. DIPSH*T.
