Nice Dave.
I do see one weak spot that doesn't happen with the USPS shoe boxes as they close at the top and bottom of the plant  - not the side like this box.
That weak spot is the cardboard is not re-inforced where the bamboo ends are situated. This could be an issue if there were rough treatment.
When I need to use a box like this I usually use a slightly different method I stole from Jon.
If you buy a tree from Jon you'll see a clever way to hold the pot in place without bamboo.

That's how to do it Dave.

Here is what Michael is talking about..........Jon's method.

Right, never thought about Jon's method, I have received several from him and never came close to having a problem. Matter of fact, I could be wrong, but I think a couple boxes had 2 pots shipped together, one at each end and secured by the same method and never had a problem. Don't forget, Jon's arrived by UPS. I would still put a stick in if shipped by USPS.

Wow some great tips in shipping plants!
Wonder how long can the plant take being sealed up like that when going long trips?

I posted a message 5 min ago but deleted it after I realized that the boxes were not Uline but Packaging Wholesalers.
I apologize if somebody read it already. This one is correct.

I received the 28x6x6 boxes from Amazon today, the price was $23.14 (delivered) per 20.
A great size to ship 2 shorter plants or 1 taller.

3 weeks ago I sold a tree in a one gallon pot on ebay and shipped it Priority which at the most it should of taken 3 days to get to the buyer I checked the tracking number a couple of times and I thought that it was odd 7 days later and it said not delivered I wrote to the person and she confirmed that it was not delivered and told me she lives in an rural area in AZ and when her regular mailman is on vacation the substitute won't delivery any packages ??? I don't understand that??? I told her that she in entitled to a refund on the shipping and that the post office would be liable if the tree died anyway on the 10th day the tree was delivered to her house and she said it was in perfect condition and didn't even need to be watered??? I'm assuming the bags must of kept the water from evaporating 

Here is an option, price seems reasonable, you should check on the quality and reputation of the company. I have not ordered from any of them as of today.

I ordered on Amazon with Prime and my price includes the shipping. 20-25 boxes was enough for me and unfortunately most of the websites charge the shipping $12-18 which kills the good deal.

Another way to be sure the bamboo doesn't poke through the box is to cut it about 1/8" short, wrap packing tape around the top of the bamboo, making a mess but folding edges over the top of the stake and taping them down to spread out the force.  Then you see where the bamboo hits the top of the box and put 2 pieces of packing tape where the bamboo hits the box.

Good point Greenfig, did you mean ships 2 shorter or 1 taller? thanks.

Oops! A brain freeze :)
Corrected...

I am checking Amazon, then weigh if I purchase enough in a year to make Prime pay off, I guess I could stream a lot of movies and read a lot of books. I usually order over $35 and get free shipping on most items. I'll check it out. Thanks.

I trade many plants in fall & early spring. I only ship dormant plants for the most part now. I would go broke shipping all that soil to my friends. I ship semi bare root plants with a freshly watered rootball wrapped in a bag and sealed with flagging tape and write the name of the tree on the tape.  then secure the plant to the walls of the box If I'm shipping many plants to 1 person I lay them head to toe with shredded paper or balled up paper between them until the box is filled so it don't move. Actively growing plants need the pots to be shipped with them. In case anyone is wondering by semi bare root I mean the plant gets removed from it's pot and about 1/2 the soil is gently washed off before bagging. 

Thanks Dave!
Great to know that in worst case scenarios like a 10 day trip the fig still survived!

The number of days in shipment and survival rates is probably directly related to the amount time the package is kept in extreme temperatures, either they will freeze or they will fry.

For dormant plants it sounds easier what edibilelandscapingsc is doing. 

If the fig tree is dormant would it be injured very badly by shaking/washing off the soil and then repotting? 

Some areas won't let you ship soil with plants in so that would help with that.
