No idea, I still haven't received my delivery yet despite it supposed to be being delivered last Saturday (it is now Thursday), the 48 hour tracking is being updated but it just seems to be boomeranging around within the royal mail system from one delivery center to another but never actually being sent out for delivery. I got in touch to advise that royal mail were causing an issue and was told to wait until Friday to see if it ever arrived, and then get back in touch, however my concern is that if it is so important that it is kept in a fridge it has now been being past from pillar to post for over a week in ambient temperatures. I love the lo-dough itself but ran out 4 days ago, hence the reason I ordered more to arrive before I had to go without. Royal mail has outdone itself in letting them down this time.
