Best time was March/April when lockdowns started and stimulus checks rolled in, insane demand back then.
I think the demand is high, see how little inventory there is for Warmoth bodies/neck in the showcase.
I'm not sure about right now but I sure did cycle through a lot of higher end gear (PRS USA) since June and can't complain about the time it took to sell them, and the price they sold for. They were a little unusual (very limited finishes) so there's that too.
If anything it seemed easier than in normal times.
Same goes for couple Warmoth bodies; I broke even on the 40th anniversary Warmoth Strat body I bought in March, which is unusual even for 'never used' gear.
You have a loophole selling via Reverb: you can set up a 'reverb store' for free and taxes are not typically collected at checkout for buyers. Of course buyers are still responsible for them during tax filing season, just like they were before online sales tax collection got enforced at major selling sites, right ?
This one is a weird economic downturn as it hasn't quite affected the finances of most (yet).
Tens of millions have lost their jobs with no expectation to get them back anytime soon (restaurants, retail stores come to mind).
Yet many other companies have actually thrived from working from home (online sales, tech companies, amazon, etc...) and those still employed there sure have a lot more disposable income from being unable to travel, not commuting, not requiring daycare for kids or pet sitting, etc...
That explains I think the unusual demand for many recent product launches that come to mind: Playstation 5, Nvidia gaming cards (they had lots of stock and expect to be unable to meet demand until early 2021), iPhones, etc...
This may go south very rapidly though, time will tell.
