An Post is expecting to make a deluge of deliveries of online purchases when postal services resume as soon as road conditions allow.
Retailers are reporting a surge in online shopping all over the country in recent days, as shoppers took advantage of unexpected time at home.
Strong online sales are expected to continue over the weekend as retailers seek to recoup revenue lost through store closures.
"We are seeing high volumes of sales from Irish and international retailers translating into packet and parcel volumes on our data systems" said Garrett Bridgeman, An Post Managing Director of Mails and Parcels.
Irish online fashion retailer Vavavoom.com said the current weather crisis has been very good for business.
Paddy King, managing director at Vavavoom, said, "We’ve seen a 25% spike in sales since the onset of the snow."
Holland and Barrett distribution manager for Ireland, Jonathan Heffernan reports a similar uplift in online orders to their Ballina distribution centre.
Mr Heffernan said there has been a huge surge in online sales over the last two days. "We’re already busy getting orders ready for dispatch and delivery."
An Post has recently opened a parcel hub beside its mail centre in Dublin which will improve capacity, efficiency and facilities for customers and staff.
"We’ll also be piloting a new online ordering and delivery service for small Irish retailers in Bantry, Ennis and Mullingar this month," Mr Bridgeman said.
