Britain’s coupon kid Jordan Cox said every year there is a Baileys price war among supermarkets which usually happens around November.
He said: “The standard price drop is usually down to £10 for a 1L bottle… or £9.50 if we’re lucky. So for Morrisons to drop the price to £8.50 is quite astonishing!”
The Morrisons deal is especially good as supermarket prices have been naturally increasing over the years, he added.
Just this week Sainsbury’s halved the cost of a 1 litre bottle to only £10.
The deal is only available to those with a Nectar Card as part of its Nectar Prices.
Meanwhile, Tesco Clubcard customers can pick up a bottle of Baileys for £13.
Are you being duped at the supermarket?
The offer is valid for delivery from now until December 9.
Supermarkets have increasingly only offered these deals to shoppers who have registered for their loyalty programmes to encourage more people to register.
Shoppers have complained that this is annoying as they could previously get the offers without needing to sign up.
The Morrisons deal is also only available to shoppers who have joined the supermarket’s loyalty scheme and have a More Card.
How to save on your supermarket shop
THERE are plenty of ways to save on your grocery shop.
You can look out for yellow or red stickers on products, which show when they've been reduced.
If the food is fresh, you'll have to eat it quickly or freeze it for another time.
Making a list should also save you money, as you'll be less likely to make any rash purchases when you get to the supermarket.
Going own brand can be one easy way to save hundreds of pounds a year on your food bills too.
This means ditching "finest" or "luxury" products and instead going for "own" or value" type of lines.
Plenty of supermarkets run wonky veg and fruit schemes where you can get cheap prices if they're misshapen or imperfect.
For example, Lidl runs its Waste Not scheme, offering boxes of 5kg of fruit and vegetables for just £1.50.
If you're on a low income and a parent, you may be able to get up to £442 a year in Healthy Start vouchers to use at the supermarket too.
Plus, many councils offer supermarket vouchers as part of the Household Support Fund.
It is easy to sign up for the loyalty programme, which is free to join.
Go to the Morrisons More website and enter a few details such as your address, email and mobile number.
Once you have registered you will be sent a More Card and can download the supermarket’s app.
You will then receive offers which will give you money off your next shop.
To get the prices in store just scan the barcode on your card or in the app.
You will also be able to earn points on your spending which can be converted into .
Once you reach 5,000 points you convert them into £5 vouchers called “Fivers” which you can spend in-store or online.
If you do not have the app then your Fiver will be printed in-store.
When you scan your card or app you will also be in with a chance of bagging a “Basket Bonus” which could give you money off your next shop or free treats.
How else to save on Baileys
To make your pounds go further you could always opt for a Baileys dupe, which is similar to the real thing.
You can pick up a 700ml bottle of Ballycastle cream liqueur from Aldi for £4.99.
A litre of the beverage would cost £7.13, which would save you £1.37.
The Ballycastle range comes in several flavours including Chocolate Clementine, White Chocolate and Milk Chocolate Peanut Butter.
All these flavours can be picked up for £7.49.
Other supermarkets including Sainsbury’s, M&S and Lidl also have their own Baileys dupes.
Sainsbury’s 700ml Irish Cream Liqueur costs £13 but Nectar card holders can pick it up for £10.
It would cost £14.28 for a litre, making it more expensive than a bottle of the real deal from Morrisons.
