Well I have found some Chinese sources of 42 - 50 grams on ebay for around $3.
Is this the right stuff? The brand is Mechanics.

So where do you get this expired paste? I have tried a few searches but no

I have had similar experience with well expired paste.
I just don't worry about it.
The issue is the solder is ground to such a fine powder that
it has a huge surface area to oxidize. As long as you keep
the air off, and refrigerate the paste, it seems to go forever.
Oh, and I only use tin/lead paste, not the RoHS stuff.
