I'm looking for shipping boxes. USPS approved shipping boxes.
I can not believe there is only 1 box made and only 1 seller. $99 for 10 boxes and shipping. $10+ for a box with a filter glued in it????
Does anyone make thier own boxes or retrofit an existing box?
An air filter is an air filter, as long as it conforms to USPS standards.
Does anyone have any insight on this?
