This will be my first buy from them but their tweet did not mention any L3+'s

And just for clarification, the are still only accepting BTH right?
This is a batch of S9 not L3+, bitcoin cash only I'm guessing as usual. I don't know why you want an L3+, the S9 makes more money (well, at least now, things change fast so who knows in a week).
I should have been keeping up with the times more. A month or two ago the L3+ was far more profitable than the S9, but now that seems to be flipped around.
Not necessarily a bad thing though since they're about to release another batch of them
