Just beware of the "binning" problem when buying from Amazon. They've been aware of it, but made no comment and may be ignoring it, for years now. This is when multiple merchants all selling "the same" item submit their goods to Amazon, who puts them in one bin and fulfills orders from the mixed stock in that bin.
Great theory, but if one merchant is submitting Shenzhen Number One Expert Quality Counterfeit and the next merchant is submitting brand name true high quality goods...you have no way of knowing which one you will get. Then there's simple outright counterfeiting and phony merchandise: For instance, every UltraFire battery on Amazon and ebay was counterfeit goods, neither took action against the vendors. And an Amazon merchant was selling "256GB" USB flash drives for two years, despite reviews stating the goods were something like 8GB of incredibly poor quality.
If the seller doesn't have a real store and/or real established reputation...sometimes Amazon is a roll of the dice. Presumably, Mr. Bezos thinks spacecraft and other topics are more important than attending to details. (sigh)
