I thought the trial users numbers 5,000 or so so quite a lot buying full price.
drop in revenue could be due to signing the new distributor rather than selling direct through Amazon or via Boots. revenue to BIEL may have fallen but number of units sold gone up.
without unit sales numbers we can never know so it is pointless argument
What I do know is that once a month one or other of the patches are out of stock on Boots.com and restocked within 3 days.
That is a sign of sales increasing as Boots.com software would be re-ordering bigger numbers each time.
