Regular and deluxe figures are on sale, but not the 2-packs. 
I noticed that, too. And of course, there's still the mystery of the Bistan / Shoretrooper Captain 2-pack that never appeared. Is Target hanging onto hope that these will turn up before Force Friday, LOL?!?!
It sounds like the DPCI for the 2-packs is being kept since that line is continuing for TLJ (that Han Solo/Boba Fett set we saw was scheduled for Fall 2017). Bad news there is, now we have to hope the old stock won't keep new stock from arriving.
It is my understanding that the same "market factors" that killed 5POA Wave 4 in the USA probably prevented Bistan/ShoreCaptain from even being made. Probably goes back to the "not very good at all" decision to release a case that was 5/8ths full of Finn/Phasma re-dos.

There are signs that Bistan/ShoreCaptain will end up in the TLJ 2-packs assortment, but I don't believe that has been 'officially' confirmed yet. I had sent an email to Hasbro PR folks, but with D23/SDCC the last few weeks no one has had time to get back to me on that yet...
