Bags: the parcel-shape problem
Three bag rows, 320–460 g. Light, but they set the shape of the parcel and can block compression.
Bags are cheap to ship by weight and expensive to ship by volume. A structured shoulder bag resists compression, so the courier charges volumetric weight even though the scale says 460 g.
If a bag is the reason for the haul, ship it with soft goods and ask the warehouse to nest smaller items inside. If it is an add-on, check the volumetric number before you assume it is free.
Before you add it to a parcel
Three bags checks
Short and specific. Each one has saved a parcel at least once.
01Weight band
Bags in this sample runs 320–460 g. Add 120 g for packaging if the row only lists item weight.
02QC angle
Ask for the bag stuffed, not flat. A flat bag hides the volume that drives the freight charge.
03Coupon fit
Check whether the coupon discounts freight or goods. A shipping coupon does nothing for a single light item.
FAQ
Bags questions
How many bags rows are in the index?
3 rows, with packed weights from 320 g to 460 g and a median of $21.80.
Are the bags weights measured?
They are warehouse packed weights from the partner catalogue where available, and conservative estimates otherwise. The QC badge tells you whether a photo set exists.
