Ordering from supermarkets online is something a lot of people cannot afford. Higher prices, plus having to order large amounts at once just does not play well with those on the low-income side of society.
The at-once thing is more of a problem*, but at least where I'm shopping, as near as I've noticed prices are identical. No markup, least for the stuff I actually shop for. Maybe I'm missing some of it, or my memory's deteriorated from not actually going into a grocery store since like... March or something... but at least for the staples I regularly tracked previously, the prices mostly haven't been higher.
*Though the minimum order is only 35 bucks at the nearest place to me offering curbside, and
as someone that's been on the low-income side of society literally my entire life, grocery shopping only once or twice a month is how I've
saved money. You do larger shopping trips to save on transit costs and time. Definitely do understand plenty of folks have more trouble doing that for various reasons, though. Still. Access to the means to make the order (internet, banking and credit/debit cards, reliable transport to get to the store and back with a substantial amount of stuff) is probably what I'd note as a larger issue.
Contact tracement revealed the vast majority of infections to occur at home and at work. Pubs and bars only account for a very small percentage.
Hasn't that had a lot to do with the pubs and bars being
closed, or at least significantly less trafficked than prior to the plague? The infections occur mostly where there's people, from what I understand.
