DH got one of the "NHS letters". Googling led me to the suggestion that he register on the uk.gov website, and we presumed this might be the database that supermarkets are basing their decisions on. The site says
"Register if you have a medical condition that makes you extremely vulnerable to coronavirus. For example, you’ll be able to ask for help getting deliveries of essential supplies like food."
www.gov.uk/coronavirus-extremely-vulnerable
But as you fill in the registration form it becomes clear that this is registering for one of the special standard parcels that they're talking about.
We don't need that, as long as we can continue to get a supermarket delivery slot every two weeks or so, so he hasn't registered.
But does not registering mean we won't be able to get a supermarket slot? Does anyone know any more about this?
