Not sure about about the refill pucks, but Pasteur's has the bowl with the tallow formula still. At least I hope so, I just ordered one after trying the tallow stick. It's a bit more expensive than the new formula from Connaught, but FOMO got me..
I bought up a bunch of the tallow formula back in May, and I was only finding it in the bowl. More expensive that way of course, but original Tabac tallow is my all-time favorite bar none. At some point I'll be PIFing some Tabac bowls.
