USPS only pickup somewhere between 10-2 M-S and its still a pain unless you do it a ton.
Don't mean to take anything away from sold (amazing product) but we are starting a company that takes care of the shipping, for anything. Check it out if interested http://shyp.co
You can leave the package on your porch, and they pickup sometime that mail day, same effect as taking it to the post office. Takes about 4 clicks to request the pickup.
It's a pain if you don't have boxes and tape and whatever, that's true -- looks like your service handles that for you which is pretty sweet.
Thanks! Agreed about the porch but that only works for items of small value.
Another huge thing people don't realize is box size. In most cases you can save up to 50% off the shipping price if you can fit your item in the tightest box possible. There are only a few sizes USPS provides for free using priority mail.
We have about 20 different box sizes to take advantage of this.
