Snapiti - how good friend is he? Would be great if he took the experiment further and now drank the same amount of A1 milk (or lesser if reactions begin again).Maybe coerce him with some good stock suggestions.
As an aside, went to buy A2 at one Countdown store in Napier last week and there were only three bottles left all expiring the next day.Asked if they had any out the back- no not until deliveries the next day. Walked over the road to the Countdown Store (used to be woolworths I think) and they had plenty all with expiries 2 weeks plus - assume they had just had their deliveries.
Hope A2 yogurt is in the horizon.
