Thanks! I know what kind of shelf you mean. When school was starting up and the back to school items were out in Target I found what they call shelves for a locker, I think--the legs fold up so the whole thing can be flat. But I bought a few to help have more space for my son's stuffed animals in his room. I also use one for snacks on our counter.Perfect! I have bags on my top shelf like that. I have a big gap between shelf and ceiling (have higher ceilings) so need to stack in some way maybe using some kind of stackable shelf in order to utilize space better.
I think it is this one below. I also noticed if you look in a Bed Bath and Beyond type store in the section where they have kitchen gadgets they also have an organizing aisle where they have some shelves that could work for this kind of thing. I keep in mind for places I need the height space you are referring to.
