Rub of green worth $5bn for US stores
Wearing the green is now big business, with the total spend on celebrating St Patrick's Day in the US now believed to be almost $5bn (€3.6bn).
And the cost of toasting Ireland's national saint on his special day alone is running at $255m (€183m).
The US National Retail Federation forecasts that spending for St Patrick's Day 2014 should grow to $4.8bn (€3.45bn), up about 2pc from last year.
This includes the total outlay on drink, silly hats and sweaters and a vast assortment of St Patrick's paraphernalia.
In 2012, global market research company, IbisWorld compiled their St Patrick's Day beer consumption statistics.
They forecast that bars and liquor stores would rake in $245m (€176m).
Since then, IbisWorld forecast annual growth for US breweries at 2.1pc, which brings the outlay on booze for this year up to $255m (€183m).
Eight out of 10 of the under 40s will head out to party and 90pc will wear something green.
