As someone who was once in the same situation. The one gallon jugs that you buy for $10 are designed to fit a rubber plug on the mouth and all the mouths are the same size. The $11 jugs that you buy which are filled with wine don’t have a consistent mouth size, so you might need to buy different sized rubber plugs for each. It’s not a huge problem, but it is a slight inconvenience.
I ordered a club sandwich all the time. But I’m not even a member. I don’t know how I get away with it.
