$2.40 on Amazon if you’re not picky about colours. $16.99 at most if you are.
Edit: I’ve been staring at these for a while, and there seem to be quite a few that people are unhappy with because they’re cheap knock-off from China that don’t spin as long. That isn’t a criterion I care about, so adjust your selections accordingly.
That said, there are still “fulfilled by Amazon” or “made in US” options that are a fair bit cheaper than this offer.
