Supermarkets try all sorts of stuff to maximise their profit. One approach is to put the goods with the strongest brands in the most prominent positions (a privilege for which they charge, of course).
Today’s invention offers a way to help level the playing field for shoppers. It consists of a user-owned periscope which is clamped to one’s trolley. This allows goods which are dumped on the lowest supermarket shelves to be inspected as easily as the highly priced items lodged at eye level.
Frugal shoppers might even choose to buy only from these lower levels. A long handled litter picker would then enable placement of any purchasable items into one’s trolley without repeatedly bending down.
