Do they allow you to come for a day to see if you like,it? And to be able to make purchases on that visit?

They allow you in without showing your membership card after 10am. So you can see what they offer. You have to go to customer care to get a day pass.. Unknown if it cost anything but is needed to make a purchase. A membership is great to have if you need gas. They always have had the lowest price in the area

Yes you can. Remember now you can't purchase anything without your membership. And the membership is only 40.00 dollars or $ 45.00 to be a member. Ok
