@Huntingdog 10/30/12 - I do drive by the stations. I do not cruise up and down streets trying to be the top guy, it's just if I notice it and happen to think about gasbuddy. I use GPS locator & Gasbuddy warns you if the price change is significant - which during that timeframe, gas went up and down $.50 in ONE DAY. You never said what price I posted - better yet. Show me a photo. False accusations.... Tisk Tisk...

@huntingdog 10/28/12 - there is also a sign on the "yellow standard shell sign". it was below premium fuel (cash/credit). this station charges more for credit than cash. the green sign is not lit up at night and the yellow sign is, which my vision 20/15 makes it very easy to see while at a red light on treat blvd going east.

Again, you just posted incorrect prices at the Shell & Chevron stations at Ygnacio Valley Rd and San Carlos Dr. Pls. drive by the stations. The prices 2 hours ago are $3.17 / 3.23.& 3.29 /gal. Any more incorrect prices and Gasbuddy will be notified as you are doing a disservice to those drivers who use this site!

ChemicalX, you posted an incorrect price of $4.29 for diesel fuel at the Shell Station in Concord at 800 Oak Grove Rd & Treat Blvd. The correct price is $4.59. The diesel fuel price is posted on a large GREEN located.. The correct price for Diesel is $4,59/gal.
