There are already 1873 German Aldi discounters in the US. Maybe it's not where the HN croud buyes their stuff (that would be trader joe's ;) ). But there is a way to get cheap fresh produce in the US now.
Unfortunately we don't have Aldi yet in the bay area, which makes up for a good proportion of HN readers. However we do have Grocery Outlet, which IMO is the best discount grocer in the US, having previously lived in the midwest and southeast.
