Research has found that people carrying hand baskets often buy fewer but lighter items, while shoppers using carts tend to purchase more products overall. The physical effort of carrying a basket makes people more selective about what they pick up. Retailers understand this behavior and often make carts easy to find at store entrances.
Even the way you carry your groceries can influence your spending. Small design choices can affect shopping habits more than people realize. Sometimes, the container changes the purchase.
