Just left Tesco a few minutes ago and all of the standard sized Star Wars figures were on a Buy One Get One Free offer.
The offer says "Jungle Figures only" but it worked for all figures for me including Rebellion, Empire Snowtroopers and the Inquisitor.
Hopefully this can help someone looking to round out their collection.
Receipt evidence posted in the comments.
As you can see, I bought 8 figures in total for my kids because I am not a complete tool who wants to use HUKD to eek out tiny profit margins by selling deals on eBay. /rantOver
