Hi there. Last time I checked, O'Malley's in Clinton did not offer Mid or Premium grade gas. They only offered Regular and Diesel. Did they change their offerings today? You just entered prices for all 4 grades; Reg, Mid, Prem & Diesel. Also, the jump from $3.77 (which you posted just after 5pm this eve) and $3.83 (which you posted around 5:50pm this eve) is quite a jump, especially when prices at most other stations are going down, not up. If your entries were simply accidental, then it would be great if you could correct them. If you're falsifying or making up prices, that is NOT okay and you risk being reported to the GB admins.

Please be advised that Shell @ 260 Lexington Ave & Fresh Pond Pkwy, in Cambridge, MA lists their cash price on the big sign and credit at the pump. Please post accordingly as to not mislead other members.
