Display location and layout: Supermarkets usually put high-profit goods in high-flow areas, such as the end of shelves, entrances and exits and in front of checkout counters. Low-profit goods may be hidden in inconspicuous places. This means that the first product you see may not be what you need most.
Packaging and combination: Supermarkets often combine different products to attract consumers, such as selling hot dogs, potato chips and soda water as packaging. However, these combinations may cost more than buying them separately, so make sure you need to buy the whole package to get the value for money.
Promotions and discounts: Supermarket promotions and discounts usually attract you to buy, but don't be attracted by discounts to buy unwanted goods. In addition, note that some discounts are not necessarily real discounts, and there are cases where the original price is raised and then discounted, but it is higher than the original. So compare the prices before finding a cheaper price.
