I add those costs into the cost of the item. People get hinky over shipping - I for one feel gouged when I see the cost of an item as reasonable, and then when I get to the shipping, know that a company is making up the cost in the shipping and handling - point in case, I went to buy jute the other day, found it on-line, reasonably priced - $6.00 + for two spools - but the shipping was over $10.00 - I immediately backed out of that! As I do a lot of shipping, I know it wouldn't have cost more than $3.00 to ship that pkg. It feels like I'm being cheated. That's just my opinion as a shopper.
