Super U supermarkets across France offered a free isotherm shopping bag to any customer that spent upwards of 50Euros on the June 30th this year. This is a great promotion which entices customers to spend a little more on their groceries to receive the bag. Isotherm bags are very useful during summer months for customers that purchase ice cream or other frozen goods at the supermarket.
Some customers who walked into the supermarket intending to buy a few products may decide to spend more then 50Euros only to receive the free bag. They can use this bag for future shopping trips or for summer picnics.
Since many supermarkets now charge for plastic bags, receiving a free shopping bag that can be reused will bring added value to the eyes of the customer. They will be able to reuse this bag over and over again when they return to buy more frozen goods throughout the summer heat.
