I have a slew of unused sheets of 37 cent stamps that can be had for 80% of face with free shipping on orders of $100 or more. Also, you get different sheets up to $300. More than that and there will be some duplication. Please email me directly to order (daveviall@aol.com) and your check, m.o. or paypal gift (as long as you pay any fees) are welcome.
