All fresh products are put in insulated bags with cooling elements. If you are present at the time of delivery, the delivery person will take back the cooling bag after delivery. If the delivery person leaves your purchases on your doorstep, you can give back any cooling bags the next time a delivery is made. If you don't return cooling bags within 4 months, we assume that you would like to keep them. In this case, we charge CHF 5 (per delivery, not per bag) to your account.
