We bought a small kitchen scale from Walmart for selling items on Ebay. If I remember right, it was only about $5.00, and we rounded up to the nearest pound also. I believe one pound is the same price to ship no matter where it is being shipped, but more than one pound will vary the price (unless that has changed).
With also being an Ebay buyer at times, I always like to see what I will actually be paying for shipping before I bid. If the shipping seems too inflated, I usually move on to find something a bit cheaper. So don't raise the price too much
