I got mine, as I said above, though somewhat to my surprise.
I find Wiggle's ordering/stock-picking/despatch less than transparent. I once asked them to explain it and the email answer was no more clear. Maybe they have changed the waffle they use but it used to seem to imply that priority to fulfilment would be given to people who paid for delivery even though one would think that delivery/despatch is something that comes after picking available stock.
I don't use Wiggle much anymore because of this - can't be arsed. Their systems are far too clever for me.
