Special offers in supermarkets have lead to just under half of Irish shoppers to overspend or buy what they don't need to qualify for the offers.
The new research, which was carried out by Coyne Research for Aldi Ireland, indicates shoppers spend an extra €9 or €10. The extra annual spend could be as much as €477, the research suggests.
It comes as runaway global inflation has hit consumers pockets and caused a cost of living crisis. Grocery prices have risen by 7.7% in a year, research by Kantar revealed last week. The war in Ukraine is one of the main factors in global inflation.

Of those surveyed, 46% of shoppers said buy one get one free and three for the price of two lead them to spend more than planned while 43% of respondents said it lead them to buy things they didn't really need. And 42% said the offers don't help them save money.
On top of this, 30% of respondents said supermarket loyalty schemes and money-off vouchers lead them to waste food. Managing Director of Coyne Research Bernie Coyne said: "Our research tells a story that Irish shoppers are beginning to question whether money-off vouchers really benefit them or provide them with real savings".
Aldi said they don't offer such deals but instead focus on offering the lowest prices possible. Meanwhile, a top economist has warned Ireland will be hit by a "creeping" recession.
