I've found them on CL. I personally plan to use just shelves with lips to hold containers on them in place. Might use some drawer slides on lower ones for heavy can goods.
The downside of that besides seeing 'clutter' is you can't lock them and any smash-n-grab thief can just grab them too. I've seen toolboxes used that lock all drawers in one which is nice. And then I've looked at file cabinets too, they are super cheap (sometimes free), and can also lock, but also have individual door latches that prevent them from opening. Paint or cover with wood veneer if they appear to 'cold' or 'office-y'.
For example, here are 9 kitchen cabinets on my local CL for $100.
File cabinet for $25: Maybe modify them to half height size on top?
Actually they make them like this, maybe I will buy this one..
