jarekvNot sure about the price, but I'd assume 69.99 is the lowest it will go regardless of how many people buy it. For the warranty, I came across some reddit threads talking about it and apparently the warranty is only applicable in China. So for people buying the keyboard in the US, there is virtually no warranty.

There's a section in the URL above talking about the warranty, but this was also back in 2015, so it MAY have changed. Not likely though.
