Our very small local food pantry is more like a free supermarket -- it is basically a bunch of shelves and a fridge where they store whatever food is donated, and then those in need can take whatever items they need (I think there is some sort of per week or per visit limit). Donations are accepted on one day and the food bank is open for clients on a different day. So, in this scenario the food bank is happy to receive basically any type of donation because they are not trying to make a whole bunch of uniform boxes to give out.
