Cardboard boxes vs mailing bags
The first ecommerce packaging decision: does the item need the rigidity of a box, or can it go in a mailing bag?
Quick answer
Use a cardboard box for anything fragile, rigid or premium; use a mailing bag for non-fragile soft goods where lowest postage matters.
When to request a quote
Ask for a quote if you ship mixed sizes in volume — we can price a box range and a mailing-bag range together for the best per-unit cost.
