I'm confused. On the USPS's website, it says I can get 25 flat-rate boxes for free. Does this mean I can just waltz in the post office, get 25 of them, and leave without paying for them?
Yep, I got a start pack of mixed sizes delivered to my house,about 5-6 months ago, but still have to use them for shipping. I found out right about the time I got the boxes delivered that using my own box was much cheaper for most of what I ship.
Many years ago I was on a forum that discovered this and a lot of users tried fleecing the USPS for tons of free boxes. Some of them got in trouble IIRC heh.
