I guess we have different definitions of scam. If you are presenting the item is such a way that naive buyer might pay more than it's worth, that's a scam to me.
Put it this way: some loser comes to the door of your elderly parents or grandparents. He sells them an $800 carport and then charges them $5000 for the 4 hours of labor it takes to assemble it. Is that a scam? Are you gonna be personally cool with a person treating your parents in this manner or are you pissed that they were taken advantage of? After all, they should have known better right?
It's a scam because they are creating a situation where a naive buyer might pay a lot more for shipping than it's worth. They are also scamming Ebay. Period. Don't come back to me with some ******** about Ebay's fees. You know the rules going in. It's a scam and you know it. It doesn't matter that it's a faceless corporation. It's not Ok to scam someone just because you don't know them or because they weren't saavy enough to catch on. There are a lot of people out there with fairly marginal intelligence that are trying to survive on their own and live a regular life. It's Ok that they didn't notice you charged $50 to send an item that cost $3.25 to ship? That's cool right? That's honorable?
How is this any more of a scam than setting a ridiculously high buy it now fee and/or a high reserve? eBay fees are way out of line, and there haven't been good deals on there for years now. Not liking the price does not a scam make
What do those other things have to do with anything? Not liking ebay's fees isn't a scam and no one said it is and you know it. Setting an ultra high shipping fee to get maximize your profit at the expense of Ebay is a scam. It's not even debatable. Many people don't like Ebay and therefore have no problem with it, but it's a scam and you know it. You can rationalize it, sure, but if you are being honest, you know it's trying to get over on someone. It's a scam.
Frankly, it's not a huge deal to me. Although I do consider it a bit of a scam, it's a pretty obvious one that I'm not likely to fall for. The only way it really bugs me is that I have to wade through the dozens of losers trying to sell HF trash for 50% more than it costs new telling you what a great deal it is.
