Coventry store sees sales of 99p cleavage-boosting bras soar by
600% in wake of breast implant saga
THE boss of a budget stores chain claims the breast implant saga has seen its sales of 99p cleavage-boosting bras and chest enhancing products soar by 600 per cent at its Coventry
shop in the last two weeks alone.
Hussein Lalani, pictured, owner of 99p Stores, said since it emerged last month that 40,000 UK women have been fitted with a type of implant that is at risk of rupturing inside the body, its shops have been inundated with consumers wanting a way of enhancing their
breasts without the risk of surgery.
He would not give specific figures of how many of the breast-enhancing products the firm had sold, but confirmed sales at its Hertford Street store in the city centre’s had tripled in
14 days.
Mr Lalani said: “It’s not just our padded bras that have been flying off the shelves, our breast lift tape, which enhances cleavages, has also been hugely popular.

Daily MailBritain could have first 'green Christmas' as climate change
warms autumn
Dr Tim Sparks, of the Centre for Ecology and Hydrology in Cambridgeshire, said: 'In four of the past six or seven years there have still been leaves on the trees in December, so a
green Christmas is not so much of a joke now.
It will only take a delay in one or two frosts and we could have one. It's possible it will happen this year.'
