Shell Gas Station Rip-Off! Very Expensive Oakdale, New York

My gripe with the Shell Gas Station on Sunrise Hwy in Oakdale is "2" problems. He is the most expensive at $4.00 per gallon, and he is supposed to participate in the "cents off" program with Stop & Shop Supermarket,BUT there is no difference since he is so high, the "cents off" is the regular price as all the other stations! So where is the bargain? ALSO, "he stops the pump from pumping gas at $1.00 before your times up! Example:  When you pay for $25.00 worth, your only getting $24.00 in the car. So  a dollar from every car, makes this guy very rich!!  Not fair! Especially with todays prices. thanks for listening,  won't go there anymore and will tell my friends and family not to. (it's happened before at this place,i didnt know of this Rip Off site. Thanks very much! hopefully others will be aware of this SCAM!
