New online delivery slots....

[OhDearWhyAmIFatterly]

Hello,
Does anyone know what time the delivery slots for the different supermarkets get released?
I have been doing an asda shop for my mum and dad, they are separated so 2 shops, as I'm 200miles away. I can't seem to get any slots now!!!
Thanks in advance!

I got an Asdas slot at 6am this morning for 15th April.

OK thanks, I'll set the alarm!
I had been staying up late but maybe early is good?

Good luck! I also find that amending the order about 5.30am is best as the new stock has come in overnight so less things unavailable.

I got a Tesco slot at 12am this morning. had to queue for 15mins but there were lots of slots. Delivery isn't for 3 weeks though

Thanks all, it seems from speaking to people in the asda queue today that Tesco has more slots....
