I don't move as much merchandise as Sean, but I have calculated the exact same way. I don't have promo materials but I do include a business card. I send cheap cards (under $5) in a PWE for $1. I've had people pay extra shipping to get the cheaper cards in a mailer, because they understand shipping isn't free. Everything else at least gets a bubble mailer and is $3.

Everything I mail goes in a top loader or semi rigid and is double bagged before it is mailed. It gets the cardboard and bubble wrap treatment if it is going in a mailer.

I have never understood someone being dinged for shipping charges as long as the item is received in same condition AND THE CHARGES ARE IN BLACK & WHITE, right there in front of you, when the purchase is made. When the seller undercharges on shipping does anyone send extra money? Of course not.

I see absolutely no problem with the way Sean does business. His .10 each additional item is actually quite fair.
