Things are starting to take shape... If only modern A4 paper boxes weren't so flimsy. They are great for stacking and carrying stuff on the trolley, but a lot of duct tape is required to strengthen them so that they won't come apart due to how little glue is holding them now.
I miss the nineties, when the they were made of double undulated cardboard and hold together with staples. Good for people that reuse boxes, bad for the environment, though
