this is usually the lowest cost in this area. If you have the BJ's card you get 10 cents off and sometimes they have in store specials that give an additional 25 cents off if you buy certain items that are on sale.
The Enfield Costco is reaming customers on 93 octane. The store manager has made gas a big source of store profit. CT has eliminated the 25¢ state gas tax thru Nov '22, yet today the 93 here at $4.79 is 50¢ a gallon higher than the Costco across the border in West Springfield. The Enfield Costco is not only keeping the entire 25¢ state sales tax relief on 93 octane, they're increasing it a lot more. Note there is no state sales tax holiday in Mass. This Enfield station should be 25¢ LESS than the Mass store, not 50¢ more!
