Exactly.

Plus $1.57 ePacket delivery from China=$7.74 for 10 pc

That $1.57 is for the USA only.
Most of the world has 'Free international shipping'...

Maybe you could send them 'Poste Restante' to Mexico, and take weekend 'south of the border' ;-)

It's described as "common anode" - to me that'd be a CA pin and, I guess, 64 cathodes.
But it's a matrix, so that "common anode" part is nonsense.

How did you decide that?
Columns Uber Alles?

Each string has its own "common anode" and "common cathode".
What does the word "common", in this context, mean?

Maybe I'm having an aneurysm. Does anyone else smell burning toast?
