I think it’s pretty much everything vaguely popular, I went to buy a Nintento switch, was a right hassle. I think it has just as much to do with the lack of manufacturing (especially in asia) as it does with increased buying though.
Anything people used to use away from home will also have been in high demand. So all gym equipment and coffee etc. Then long life foods from super markets. Will be interesting to see if there is an impact on gyms after lock down ends as people want to still social distance and potentially have more equipment at home so dont need to go…
I don’t know if hoarded. But something that went into demand is Arts and craft both kids and adults - even just basic things like paper and paint. A lot of eBayer’s multiply the usual price x10 - x20.
Probably worth thinking about what people are going to rush out and buy or services they will use when shops start to open gradually, the lockdown ends with social distancing rules in place
