We bought this as we dont drink milk and got fed up with throwing away most of a carton after making a few cups of tea for visitors, so as its UHT imagin our dissapointment to find it had a use by date of just 4 weeks ! In my local Tessco the 500ml cartons have a use by date of 6 months ahead, so guess we will end up throwing most of this away ! VERY dissapointed. simon. UPDATE. I placed this review on saturday buy midday monday (the next working day) the supplier had contacted me by phone to explain that the pack with the short use by date had been dispatched in error and an order with around a 4 month use by date (this im informed is around the maximum use by date) would be delivered by thursday, not only this but as a goodwill gesture they refunded my payment! so 5 STARS for the follow up service and customer support. simon.
