@Anouk Costco gas. Cheaper than surrounding gas stations and premium and super premium (89 and 91 octane ) are cheaper. If you apply for the Costco credit card. There is additional $$$ saved 5% specifically on gas - but could be higher. Also they have m&ms in bulk. And our Costco has winter boots, clothing, food stuffs, fresh as well as prepared (terrific seafood if you are into wild caught salmon) and pumpkin pie season is here.$9.99 for a ginormous one-too big for a dorm sized fridge! Enjoy!
