After running my umpteenth grocery delivery with its dozen of 1-2 items plastic bags (why stores, why?), I decided there had to be a better way. Following the example of the very stored I was picking up from, I've implemented a similar bin and cart system. I keep this cart along with three plastic totes in my car's trunk which I then load up and haul in one or two trips to customer's door instead of dozens.It collapses and stores in a remarkably tiny package despite its high fully-extended carrying capacity. It can easily carry three 12-gallon totes loaded with groceries over typical city terrain (roadways, sidewalks, doorways, etc.), so a little actual luggage shouldn't be a problem. The bottom portion extends an extra couple inches to fit longer items, the bungee straps will securely hold most items, and the handle locks into a couple of heights to accommodate different users/uses (kids or adults, walk-along or tow).
