Bests & Worsts Reviews from Amazon

It says at the description ‘the style may vary’ apparently that means they can send you ‘any’ color, literally whatever they have left in stock, it shows a red one but you may get green or black or whatever color you actually don’t like or want to use. I called Amazon for this and told them they need to put more detail for this products’ information If you were buying a nail polish would you not check the color first? This doesn’t make any sense.
