This isn't exactly where this belongs so feel free to delete this. I'm mildly infuriated there is no usable alternative to Amazon.com. I'm more than willing to buy products elsewhere, but it's so easy to default to Amazon. Please help.
Amazon sources are equally hard to verify. The only difference is Amazon has a little more customer satisfaction power (by returns to a main warehouse) than ebay (now warehouses but still favors the customer). There's continuously new ways to get counterfeit product sold on Amazon.
On the subject of returns (Amazon and others) Climate Town just did a video on it, and holy shit. Even knowing the problem the scale is hard to take in.
