Although not based in the UK, the same 'problem' here in the Netherlands. There's only one big toy seller left here (due to the crisis?) and after TFA they are reluctant selling toys from new SW movies. Now TLJ toys can be bought for bargain prices (about 4 GBP each) and they sell many Rose, Hux and Kylo figures and a few Stormtrooper, Chewbacca and Rey figures. And yes, even Luke Jedi Master for about 4 GBP
Also saw a few B-Wings for bargain prices and of course this kind of commtech reader stupid device (can't remember the name) with the Kylo figure.
Managed to buy me some R1 figures for about 2 GBP (K2SO, Kanan Stormtrooper and R1 Stormtrooper). Because they do look descent, not because of the movie (don't hate R1, it's ok by me).
But no Solo figures and vehicles in the shop. Mhhhh, strange is it
