Melbourne, Nov 2 : Although the ‘art’ called ‘shopping’ has no ‘science’ behind it, a mathematician has come up with the prefect formula for spending spree.

Roger Bird’s algebraic formula takes in certain factors, which include time constraints, the number of shoppers in the group and the amount of spending money, to calculate the best conditions for a shopping trip.

The researcher from Bradford Education Authority, in Britain, devised the formula based on results of a shopping centre survey of 1000 people.

As per Bird''s findings, the perfect excursion involved a visit to several clothing stores located close to each other between 9am and 11am on a Saturday, reports the Daily Telegraph.

Far from the stereotype of dingy, dimly lit and well-hidden sex shops, the Little By Little Adult Concept Store''s approach to business at Hillcrest is rather unique.

However, the new business has been caught in a battle for survival with Logan City Council and some surrounding businesses.

The sex shop also neighbours the New Life Lutheran Church.
