Like the product shop for it at sainsburys aylesford but lack of low level or zero nicotine means I have to e mail for low level nicotine,suggest you stock the major outlets with low level and zero nicotine options,have been to many outlets but all have med and high nicotine choices ,nothing else.Make greater play of the fact the product. Is made in Britain and not in a back street lab,I personally am willing to pay for a premium Brit made product.Although you can't guarantee complete safety,labour heavily the positives.......less contaminants than cig smoke.
