A combination of shopping bags designed to be used instead of plastic carrier bags. The set start off as several slightly smaller subsidiary bags being carried in one main larger bag. The smaller bags collapse flat and fit within the larger bag. The front and back and bottom of all the bags are quite rigid, being lined with semi rigid/rigid material. The side panels are flexible and fold into the bag enabling the bag to easily collapse flat by pushing the bottom semi rigid/rigid panel up. The semi rigid/rigid section secured in the bottom of the bags flips up to allow them to fold flat. On filling, the bottom drops down to give the bag a boxy rigidity. When the bags are collapsed flat, they require no reshaping and they slide easily into the larger bag ready for reuse.
