Booking delivery slot online for Dec/Xmas?

[motherofluvlies]

Is waitrose the only store allowing xmas week/Dec grocery delivery booking slots now?I cant seem to get any further than 3 weeks in advance with T,s or S.
W is completely booked for 23rd Dec in my area already!!

24th October for Ocado. I'd be very careful with Twatsco and Asda as they usually deduct the balance when you place the order and put it into a holding account. There's threads on here about people trying to get a refund. Ocado take the payment after they have delivered.
