I can see what's going to happen.  
We'll all send our large letters Registered Post ... which of course require a signature on delivery.

Now we are all going to be hit with a huge increase in Items Not Received .... because the things have been carded (if the Postie does the right thing) and returned to the Post Office.  

The whole thing just creates more work for everyone .....

1. The sellers having to pay more for postage and upload tracking numbers ....

2. The Posties having to return things to base ....

3. The buyers having to pay more for postage and yet still have to go to the Post Office to pick up the item, if they aren't at home to receive.

4. Ebay CS with the increased number of unhappy buyers and sellers.

I have sent 100's of large letters since starting selling here .... with less than 1% causing problems.  

These changes are GOOD BUSINESS THINKING!!!! ..... NOT
