Is NI cheaper for buying alcohol?

Tesco is certainly not cheaper in NI if you have an ie clubcard. I got wine here at €12 for €9 with clubcard. In NI the same bottle is £7.75. That's marginally more expensive. ASDA had the same prices as Tesco NI but they can have deals on some days.

Yep, thats the go-to deal every time

Roi shoppers should note that you often need a Nectar card for these 25% 6 bottle Sainsburys deals. If you don't have one, you may be charged normal price without the discount.

I know because I was once asked by one such person if I had a Nectar card and could they use it. They were shocked they didn't get the 25% off, cashier explained to them, and then said "if you want to borrow his Nectar card I'll look the other way".

Are you going to Newry?

If so, have a look at the deals in the shops but for regular beer also look at either of these (they are 5 mins off the M1 at the exit for Jonesborough):

The outlet place is in Banbridge which is a good bit north of Newry. Jonesborough is south of Newry, just over the border.

Traffic in to the shopping centres in Newry is a disaster on December weekends.

Carlsberg is 3.4% in NI. If you're calculating savings you should bear that in mind, it's misleading to compare directly to the Irish price of 4.3% Carlsberg

There are savings to be had for sure. Asda have a 3 for £23 offer with various 10-packs of beer in it. Including some with 5% ABV. Last time I checked that was where the best value was to be had, with the likes of Heineken being around half the price of the comparable m.u.p price here (factoring in that it's stronger up North). I haven't checked lately so maybe there is better value elsewhere.

Asda also have some 4 for 3 and 2 for £10 offers that give savings on some decent beer like Duvel and some of the British craft brands. Not anywhere near half price but decent enough savings.

I have no idea; I was surprised myself!

Some do - Carlsberg and Corona cans do, but not always. They’re the only two I’ve seen with them, it’s likely there’s others.

Likewise, you’ll occasionally get Coca Cola products (all varieties of Coke, Fanta, Sprite) in cans in NI with the Return logo - but there’s no consistency to it it seems.

If a deal does need one, I'm absolutely certain you can get a Nectar card in-store anyway
