I wouldn't bother buying them unless they were High Speed Steel. I have used a
lot of hardware-store taps over the years and most of them are rubbish sutible
only for cleaning up existing threads in soft metal.
I also am a fan of "gun" taps, which are cut at a negative angle on the point
and push the waste ahead of the tap, preventing the jamming and breakage for
which taps are known. If you are tapping a blind hole, I suggest you start it
wth a gun tap and finish it off with a bottoming tap.

Just don't use it in cast iron. :-)
