For instance freezer bags, or toilet paper... I'll probably only want one roll, and they usually come in at least packs of 4.
Or even food. Let's say I only want a few ounces of olive oil, not a whole bottle.
Do stores along the trail cater to that sort of thing? Or do you just end up going in with people on stuff, or just giving the excess away?
I'm assuming it's pretty straightforward once you get there and see how everyone else is doing things. I've never been on the trail and all my stuff is totally ready to go, so I have nothing to do for the next few weeks but get excited and wonder about all the minor little details : )
