Hi, The big problem with using the Paypal postage on line feature is that your local post office will not make any money from it only Paypal / Ebay does.

This means that if your local post office is a small one it may close down. 

I thought that they still got some sort of money from it, but after chatting to them I found out they are loosing quite a bit on income because of it.

If you use a busy city Post Office then don't worry. It will save you tons of time queuing (unless you need certificates of posting) and people moaning behind you :)

I found it very easy and quick, and especially like the 'do not display postage cost'  option . Keeps the people complaining that you've charged them £2-50 post & packing but the label only says £2.28.

Summary: Don't use if you have a small local Post Office - great for City Dwellers.
