I think this wouldn't seem dishonest to me IF Ebay listed it as shipping AND handling fees. Minor point for sure, but it makes things seem more up and up. I, just last week, dropped 4 dollars on bubble wrap, a buck on tissue paper, and 2 dollars on tape...I didn't factor that as shipping fees, so I ate the cost. I guess as a business, it would be a poor idea, but I was selling off a couple of things just lying around unused.
Why is it dishonest? The price to ship is stated up front. You either agree to it or not. At times I will pass on auctions for items where the shipping is too high. Often that is used to make up for a low starting price. Say on new items where there is a pretty set market price. You might see an item start at $10 cheaper than you can buy it anywhere else. And then the shipping is $15 when it ought to be $5. It all comes out even but it is a game some play. If you don't like that game, don't buy from them. I pass on those myself.
I know what it costs to ship stuff and can tell if the shipping fee is pretty close to being right. I don't sweat a couple of bucks. Like I said, I look at auction price plus the shipping as my cost of the item. As Buzzard said, I look at what it'll cost to get it in my hands and that is all that matters to me. It is either a good deal at that price or not.
