The cost of delivery methods is calculated based on the actual weight of the parcel, to the exclusion of over-dimensional parcels.
In this case the delivery cost is calculated on the dimensional weight. Parcels are considered to be over-dimensional,
if the sum of the three sides of the parcel exceeds 150 cm and the weight exceeds 2 and more times the actual weight.
In this case, the calculation of the shipping cost is based on the dimensional weight of the parcel (length (cm) x width (cm) x height (cm)/5000),
but with a special reduced tariff.
