On the other hand, as a seller, I do add a small amount to the actual shipping cost. I take great care (and use lots of tape and packing materials) to be sure my stuff is going to get there in one piece. My time and materials are not free.
IT'S FREE!
Thanks for being an honest seller. Reasonable handling charges are not an issue for me. Shipping charges are pretty well set. A $5 item with $10 s/h is generally a scam.
