If I were to just go to the Wine Source I would walk or bike (though they don’t have a bike rack!!!), but I just happen to only go when I’m on the way home from something else that I usually drive to. It’s definitely not, as other commenters said, because I’m buying cases of wine lol, I only go to pick up a discounted 6 pack. Though I have fit like 6 750 ML glass bottles in my bike paneers before, it’s not hard at all, they give you little sleeves on the bottles to stop them from clanging around.
