While researching maildrops, I found this info from 2001. It is accurate as I have just placed an order for “Box 7”. The order confirmation states 7-14 day delivery period…
Ahhhhhh – All so exciting!!! It’s all falling into place…
“Attention prospective thru-hikers: you don’t have to scrounge around (or --gasp-- pay) for all the boxes you’ll need for your mail drops! I’ve read in several journals that folks have had a hard time finding shipping cartons, but you can get them free from the US Postal Service (not only that, but they’ll deliver them to your door!).
Just go to http://www.usps.com and hit the “Buy Stamps and More” link on the left. Then hit the “Order Shipping Supplies” link. On the new screen, hit the “Order Supplies” link on the left. You’ll be asked if you understand that the boxes you order have to be used for mailing stuff (don’t use them when you move into a new house!), and then you’ll get to a screen that asks what type of mail you want. Hit the “Priority Mail” button (Priority Mail is anything sent First Class that’s over 13 oz. You want Priority so that you get free forwarding in case you get ahead of your maildrops while hiking!). Finally, you’re on the order page. I recommend “Box 7”, which is a good size for hiker supplies. You can even tape two of these together for larger shipments (even the tape is free). One word of advice: order your shipping supplies at least a month before you need them.”
