Shipping cost formula
Effective shipping cost = postage + packaging + handling effort + risk buffer
Example 1: standard parcel
6.99 EUR postage + 0.80 EUR packaging + 0.40 EUR handling + 0.30 EUR buffer = 8.49 EUR
Example 2: fragile item
7.49 EUR postage + 1.20 EUR packaging + 0.70 EUR handling + 0.50 EUR buffer = 9.89 EUR
