Supermarkets are expected to cut prices on some products.
It's as major retailer said it's dropped the price of 700 other items.
Last month Government officials met with the heads of supermarkets asking them to drop prices.
Charlie Weston is Personal Finance Editor with the Irish Independent, he said "some of the reductions are small [and] a lot of them are big.
"About a third of them are own brand and the rest are brands that people are familiar with.
"Watch this space - kind of thing - I expect today you'll probably see a reaction" from other supermarkets.
"It's a cut-throat competitive business. And they all watch each other like a hawk and match prices."
Figures earlier last month from Kantar showed that grocery inflation is still at more than 16%, despite the rate slowing in recent months.
The economy's overall inflation rate is at around 7% over the past year - however in supermarkets since February prices have gone up by 16.5%.
The rate is slightly down from last month, however, it doesn't mean the prices are coming down, but rather the rate the prices are going up is slowing.
