A few updates, I do online printing of labels now so purchases will go out much more quickly (same day as opposed to 1-3 days after receipt of payment)
Not as a result of this but of much importance, I am raising my shipping rates. It costs me $3.85 to mail something registered in the US, and I charge $3.50, therefore I am not only losting that bit of money but also losing whatever PayPal charges me... so from now on I am charging $5.00 flat rate and will take any damages from PayPal.
For outside the US my new registered s/h flat charge is $10.00.
Regular mail is the same, $1.00 s/h for US or worldwide.
