Yes, each person places their own order, I used to do it online and pay online with credit card. You order by the deadline, and indicate what delivery route you are on, and name of the drop point. I think the entire drop point order had to order 400 dollars, IIRC.
It is presorted for each person, for sure the non-perishables and IIRC also the perishables. It seemed that the driver would stay in touch with the drop point for updates, but would also just drop into an open garage, or front porch, and drop point did not have to be manned.
there was a fair bit of variability in when to expect the order, ie, originally at 10 am, arrives at 4, etc, and a couple of times delayed to next day. That was one of the reasons I stopped doing it, because I could not plan my day with the pick-up involved, as it had to much variability.
Would be willing to try again though, if there was interest. The prices in their sale flyers were usually quite good. I also remember being frustrated with them often being out of what I ordered, and then missing out on the good deal, because we only ordered every other month or so.
