Bought Ariel actilift gel (24 washes) for £1.96 a bottle. It's most likely an online glitch and very few if any (if not yet fixed) will get lucky. Here's how it worked out for me - a while ago, this: http://www.hotukdeals.com/deals/ariel-gel-888ml-was-6-97-now-1-96-bio-colour-febreze-morrisons-2395470 deal was posted, I tried my luck then (had ariel gel in my online trolley, but as there was no stock left, it did not let me check out), so I gave up, didn't want to shop for anything else, closed the tab and did not shop online at Morrisons since (this is most important part).
So now I decided to buy a few boxes of Fosters, they are box of 20 for £10 BTW, went on Morrisons web site and noticed, that I still had load of Ariel gel left in my trolley from previous attempt to buy it.
As all was forgotten I was removing them one by one just to notice that the cost of the trolley reduces by £1.96 instead of a £5 (current deal is £5 a bottle or 3 for £10).
I decided to try my luck and check out, and it worked. I thought if it's a luck I might as well push it to the max and ordered 20 bottles, which is max amount. OK, not being a too big of a dreamer I doubted it will get delivered, but today it did, I GOT IT ALL! And for 20 bottles I paid £39.20
Will not be a deal for everyone, but that's how glitches work. I just wanted to share with you guys, as you all have saved me hundreds of £ and who knows, maybe few of you will get lucky too.
