I also find it easier to trust eBay. It's not perfect by any means, but overall it's a better shopping experience than Amazon. Hard to pin down why exactly, because 90% of both sites is the same cheap stuff. It just feels like eBay isn't as aggressive in pushing me towards a specific item it wants me to buy, so I have an easier time finding what I actually want/need. I guess it's because Amazon always wants you to buy from them rather than a marketplace seller, while eBay doesn't care which seller you buy from as long as you buy something, and you're more likely to purchase from someone if you find the correct item?
