MIL is recognised as vulnerable with Sainsburys, emails confirming this, up until now has had no problems at all booking slots. She's hoping to get a delivery for next week but whenever she goes to check out it says 'slots for these dates have not been released', usually she can book a week in advance without any issues so we're wondering if it's more of a site/system error at the moment. Has anyone else been able to book a delivery in the week 20th - 26th April?
She only gets a delivery every 2 weeks so she's not trying to book twice within the same week or anything like that.
