You are billed on size, not weight. Remove shoe boxes / vacuum pack to cut.

Why your 2kg haul billed as 5kg

A 40×30×20 cm box = 24,000/5000 = 4.8kg volumetric. Even if items weigh 2kg, carrier bills 4.8kg. That is the #1 surprise cost for mixed sneaker+box hauls on Kakobuy.

Remove outer shoe boxes, keep dust bags → often -30% volume.
Vacuum hoodies, keep bag boxes if you care about shape.
Split >4.5kg into 2 parcels to dodge volumetric spike.
