Should the discount show when checking out?

I think they must just overcharge the rest of the time as Sainsbury's are always doing this offer, same with their Tu clothing, every few weeks it's 25% off - I reckon people who buy at the full price are subsidising it.

Doesn't seem to work. Are there any conditions that need to be met for the discount?

Cheers op another new account opened and £20 off £100 code used

No point me doing it, everytime and I mean everytime they deliver only 5 saying that 6 weren't available. Funny that isn't it, just so I don't get 25% off.
Thanks for letting people know though OP, heat added

Any new customer codes available?

Looks like Tesco have matched this offer now.. So more choice, similar prices across the board

Always near a bank holiday they do this. I'll be checking this out this weekend. Morrisons haven't done this offer this year which is surprising

From the site

"Add to your trolley the stated combination of products from the list below and you'll only be charged the offer price at checkout. Promotion not in all stores"

I don't live near a Sainsburys and I don't drive so it wouldnt be worth the cab fair.

Picked up 12 from here and 12 from Tescos. that should last me 2 weeks!

Combine this with the 10 x nectar points offer.
