The Government is expected to formally sign off on legislation banning the below cost selling of alcohol this week.
NoffLA, which represents off-licences across the country, said it is important that alcohol is sold safely, to discourage binge-drinking.
It could be the summer before the legislation comes into effect.
NoffLA spokesperson Evelyn Jones says below cost selling of alcohol can lead to excessive drinking.
"For us to have a sustainable trading environment and sustainable industry going forward, we need to promote the safe retailing of alcohol," she said.
However, she also mentioned the business impact that below-cost selling has when major supermarkets ca afford to use it as an incentive to bring customers in.
"Using alcohol as a footfall driver to sell other, dearer grocery products in mixed-trading environments wouldn't really be seen as the most responsible method of retailing."
