Someone also reported this for sale in another Sainsbury's on the facebook afol group, also reported other Sainsbury's being full price

Thank you! I went to pick one of these up and ended up spending lots buying loads of other reduced sets :confused: at one of my locals.

Sorry! What else did you find? Didn't see anything else at mine except one empty space on the bottom shelf but not sure what that was for!

I got a few of the new batman movie sets which were all reduced to clear at Half price including a Lego juniors one, two of the new mighty micros for £4.50 the superman vs bizzaro and Wonder Woman vs doomsday and a batman vs superman kryptonite interception for £15 they had a lot of ninjago reduced as well!

Can confirm this. Saw these at Bangor, Co. Down:
70904 Clayface = £15 (Was £30)
70903 The Riddler Riddle Racer - £20 (Was £30)
76045 - Kryptonite Interception = £20,
76053 - Gotham City Cycle Chase = £10
70623 Ninjago (Half Price) £12.50
70624 Ninjago (Half Price) £12.50
10823 Duplo Batman (Half Price £12.50

Thank you, just came back from the other Exeter store (Pinhoe).

They had about 10 of the Gotham Cycle Chase sets, they'd sold out of the reduced Ninjago but I did find 3 of the Lego Batman Movie sets reduced (Penguin's Car £20, Riddler's Car £20, Clayface £15). None of the mighty micros or other sets were reduced for me.

That's okay glad it was helpful! I don't normally get any Lego bargains like this so I was quite surprised. It's strange how certain stores reduce items that others don't.
I'll be going to check my other local later.

good find op, heat added

Sainsbury's in taplow have all the new girls superheroes dc Lego for half price

Left Milton Keynes Sainsbury's a few hours ago and there was only one cycle chase left in the clearance section.
