It's not that big a problem, really, here. It's more of an annoyance than anything. I must get a good 5 PMs a day with someone saying "but the shipping". Like 3/4 of the people never even reply when I explain it to them. At least half the PMs I get are from people who say "I want X, Y, Z, and I think A....but the shipping....".
Like I said, shipping is generally cheap. There are a few exceptions; one example was the Diablo 2 gift set I was selling. Shipping for that and Lord of Destruction was estimated at $8 (and will probably be about $1 or so more than that) because it was heavy and bulky It had 3 strategy guides in two full-sized PC game boxes. I sold the games for $15; if the price of shipping were included, I would have LOST more than half the money I originally sold it for.
If the shipping is a concern for you, then it's an even BIGGER concern for me. Paying $15 shipping on an order of like 10 items isn't that excessive. It's a lot to pay, maybe, in terms of spending the money, but (a) You've spent more on the order itself, and (b) It's cheaper than paying to have it all shipped seperately. Or shipped from someone on eBay. That doesn't translate to "better you than me", though; I'm selling a whole bunch of stuff to a bunch of other people. If 5 people each paid $2 apiece for their items to be shipped, that's not a lot for them. However, if *I* paid $2 shipping for each of those 5 people, I've just lost $10. $10 out of my own pocket, and I haven't even been paid yet. And $10 LESS the amount I would actually be getting once I do get paid.
Me charging shipping is totally fair, and shouldn't really be a big deal.
