Советы по снижению стоимости доставки

1)Избавьтесь от оригинальной упаковки, например, если вы покупаете пару обуви, можно избавиться от коробки для обуви, что сэкономит много на объемном весе.

2)Стоимость доставки обычно взимается за каждые 0,5 кг. Так что, если вы покупаете продукт весом всего 0,1 кг, возможно, стоит рассмотреть возможность покупки 2-3 штук за раз, что не увеличит стоимость доставки вашего заказа.

Объемный вес

Объемный вес относится к общему размеру посылки и измеряется в объемных килограммах. Объемный вес можно рассчитать, умножив длину, ширину и высоту посылки (в см) и разделив эту цифру на 5000 (некоторые перевозчики используют делитель 6000/7000 и т. д.).
