Advanced Lemon, same as the pic. 12 for £1. Better than ASDA or Amazon at the moment where the best offer is 8.8p and you have to sign up 5 items to subscribe and save for that (platinum version though). ASDA's best is 13.4p for the same tablets but you have to buy a pack of 67.
Despite buying some big bags in the ASDA clearance I put those in storage in one of many unmarked boxes and then ran out :D. So I remembered these from a few weeks ago, popped in yesterday and they're still stocking them. There's some on the dishwasher shelf and they had some by the entrance on the shelves. They also do 10 finish for £1 which I presume people know about.
I thought I'd add them as they're nice small packs, great price, not a cheaper version and I find fairy better for quick washes than tablets.
