I must be one of the last people using eBay-PayPal's shipping-postage labels system. I couldn't believe how easy it is. So impressed was I that I made my first and only eBay Guide describing it and encouraging its use. You can read it by clicking this:

You can vote that it was helpful by clicking the "yes" button at the bottom of that page.

I also compare it to the Post Office's Click N Ship set-up, which I find inferior to the PayPal set-up..

One of the great things about it is that you don't have to stand in line at the post office anymore for most things. You can just toss your parcel or package (which you can insure yourself) into any post office mail box, any package of any weight, as long as it can fit into the mail box! As I put it:

¶ best of all, perhaps, you can drop your packages off into any outside Post Office mail box -- any package that will fit, any weight. There is no 13 or 16 ounce post-911 security limit because it is considered metered mail (it can be traced to you). No more standing in lines at the post office, or did I say that already?
