I am a true professional philatelist, doing this for a living since 1995. 

I have divided collections into auction lots and described auction lots for many major auction houses. 

In other words, you get what you pay for. 

SHIPPING

Both domestic and international is by USPS.

If you purchase multiple items and you wait for me to send you an invoice then I am pleased to combine shipping.  If you do not wait for me to send you an invoice then you will pay more for shipping.
