The organisation representing independent grocers says major supermarkets are displaying 'gross irresponsibility' by giving money back coupons to customers who buy alcohol.
Two large chains are offering to partly reimburse shoppers for drink purchased in their stores this weekend.
Dunnes Stores is offering 20% back in loyalty card vouchers for shoppers who buy a range of items, including drink. Tesco is reimbursing members of its loyalty scheme 25% of the price paid for all beer, wine and spirits.
RGData says promotions like this encourage the sale of alcohol and it is calling on the Justice Minister to fast-track legislation to ban such offers.
The organisation's Director General Tara Buckley said the supermarkets were showing no regard for concerns about the irresponsible sale and marketing of drink. She said that both stores were treating alcohol like any other product for sale in their stores and were more interested in the bottom line than in demonstrating corporate responsibility.
The recent Intoxicating Liquor Act contains provisions to restrict the supply of alcohol at reduced prices and makes specific reference to the use of bonus points or loyalty cards. However, this aspect of the Act has not yet come into force.
A spokesperson for the Department of Justice confirmed such measures would be introduced and said the Minister was in consultation with the Attorney General about drafting these restrictions.
Both Dunnes Stores and Tesco Ireland have refused to comment on the issue this evening.
