You are purchasing a used se-tenent set of 15, #3184 a-o Celebrate The Century Stamps, 1920's, 32 cent, off paper.  The scan is a sample.   Shipping is $.73 within the United States, outside the United States is $1.65.  I do combine items to save on shipping costs, I only make adjustments for weight changes so you can sometimes put several together and it has no impact on shipping costs.  Thanks!

Bonus:  I use stamps on my shipments.
