Mitchum Ultimate cream deodorant is currently on offer 2 for £4 at Sainsburys (this particular deodorant usually costs £5 for one!). Looking on their website, it is also part of the "Spend & Save" deal which means if you spend £20 or more in one transaction, you can save £5.
I have just tried adding 10 to basket online, and total cost came to £12.50 for 10 (£37.50 discount it says)!!!
I don't know how long this will last and I have a feeling they change deals on Tuesday, so today might be last day to get this deal.
