Chefs usually go out of stock but it usually comes back so just keep checking.
I've been searching and found nothing.
The ecigshop look like they've been having a LB sale and if I'd noticed before they ran out I'd have stocked up for sure @ 100ml for £3.
I registered for an email notification from Chefs when it was back in stock and they contacted me a few days back. I've just bought some and they still have it at the moment.
