The original deal ended on Dec 2, but has been revitalised for a second promotional period, starting on Saturday.
Vouchers are available from Wine Rack’s website and in a text-in promotion. They’re also being distributed through third party online media.
Parent company Thresher said the new promotion was as a result of “unprecedented public demand”.
Jonathan Butt, head of global sourcing for Wine Rack, said: “In a response to customers who were unable to redeem their vouchers before the end date the business has taken the decision to reintroduce this special offer.
“Given the exceptional economic circumstances that the country is currently experiencing, shoppers are searching for the best deals on the high street.”
