Media rate items -1st item is $3.35 -each additional is 50 cents, mix or match... they must all be media rate items (not first class please) to apply. Flat Rate Priority Boxes are $10.75 -Flat Rate Envelopes are $5.50... I utilize the least expensive mode of travel whenever possible. Please notify me if mailing a check or m.o. so I may anticipate payment. Thank you.
