The idea is that shoppers could use the UpCart like a storage system. Heavy things go on the bottom, lighter things on top and the bins can be swiveled in and out of position for easy access. Each bin could even be lined with a shopping bag to save time at the checkout. Obviously, there are a couple of problems here. First of all, the vertical design with the bins probably won't reduce your footprint in the aisles all that much, and second, it would most likely be prone to tipping over if loaded incorrectly. So, I woudn't expect this concept to show up in your local Walmart anytime soon. [Industrial Design Served via The Design Blog]

I'm not quite sure what the point of this thing is, however. At first I thought it might be a good way of transporting groceries in the city when you don't have a car, but once you load it up with groceries you obviously can't get in it to bike home. So other than the Idiotarod, I'm not sure when you'd use this. Pretty awesome nonetheless. [No Quedan Blogs via NotCot.org]

Two things. One, 300 pounds? People (the non-disabled and non-elderly) who use this thing would probably weigh a bit more than 300 pounds. Two, that's really not enough storage space to hold all the food for a 300+ pound man.

Also, surely anybody who uses this sit-down shopping cart doesn't have gams like that. – Jason Chen
