anyone I’ve heard talk about it think a lot of their prices are outrageous without the club card! I’ve had the odd “real” reduction but for the most part the club card price is the same as the normal price in Dunnes ime.
Tesco, overall, is cheaper than Dunnes. However, you definitely lose on the range of options, and I found that Click & Collect became more irritating as there were too many items they didn't have, so I'd have to go to Dunnes anyway.
Dunnes' range has improved, I spend the extra to get James Whelan meat for example, as I do think it's worth it.
I shop in various Tescos around Dublin / Kildare (work, kids' match locations as well as my local Tesco) but only for top-up shops + specific items & that's when I'll avail of the club card offer. Recently Nutella for example was €2.25, €3.85 in Dunnes. That's clearly a non-essential item 😀 but it's the kind of purchase I'll make using the Tesco offer & won't in Dunnes.
I shop with such efficiency & to a budget in Dunnes that I know exact prices. Similar to Tesco & everywhere else, the price jumps from week to week are incredible. Like € in the difference, not cent.
Dunnes works for me as I can manage the voucher system to my advantage - but it really just makes my shop affordable, not actually significantly cheaper
