What drives mailer box cost
For most orders, pricing changes because of four main variables: size, quantity, print complexity, and material choices.
The fast pricing framework
### 1. Base cost
Every supplier starts with a baseline unit cost.
### 2. Size multiplier
Larger dimensions usually mean more material and higher shipping exposure.
### 3. Quantity discount
Higher quantities reduce unit cost, though not always linearly.
### 4. Print and eco surcharges
Full custom print and eco-specific requirements usually add cost.
