So...just make sure you fill in enough to cover your shipping costs. I've burned myself a few times and was a few dollars short in the shipping. In those cases, you gotta eat the cost. You can't go back and ask for more.
I think the inflated shipping is also the "loophole" to get around eBay fees as (and correct me if I'm wrong) the fee is calculated on the sale price before shipping costs are added on. The $0.01 product, with the $20 shipping.
