Avante, thank you for your very interesting post.
Selling on ebay I only charge $1.60 over actual shipping cost. 60 cents for delivery confirmation and $1.00 for me just in case I make a mistake on weight when packed. I want to purchase Marx train cars and every time I see the shipping for an 8 oz car is $8.00 I cringe and pass over the seller. But there are people that will still buy just because the total doesnt look so bad.
