Re: Thinking of starting a box pass.
I'll be sitting this out but just something I think would work well for this is using a box that will fit inside a reasonable size flat rate box. That way the box will arrive, you open the flat rate box take out the exchange box and swap what you want then put the exchange box into another flat rate box and ship it to the next address.
