I hate high shipping costs. Even if the total amount ends up a little cheaper, I still have to weigh the savings cause if I had to do a return, they only refund the actual price of the item and not the shipping.
That's why I hate items that sell for one cent on eBay and then shipping is like $9.99. If I have a problem with the item, I'm pretty much screwed in that I wouldn't waste my time to complain to get back a measly penny for the actual selling price of the item. I'd much rather look for the auction that sells the item for $7 and charge $3 for shipping for obvious reasons.
