I was looking to buy a decent table saw, summer 2020. Was interested in the Dewalt DW745 or its replacement. Watched a video by a guy called Mitch in the states, he talked about prices of $259 in 2018. Here in UK in 2020 the cheapest price was £449 or $550, more than twice the price! The other makes were similarly priced and there were no deals to be found. I put it down to coronavirus reducing supply so decided to stick with my old saw.
Then I spotted a deal, scheppach 216mm, cheap £89, no soft start, light so fits on shelf and is transportable, has legs if needed, fence a bit fiddly, greatly improved by changing the blade. Sold my old saw, 300mm contractor for £140 so freed up some space and can easily put the saw in my car. Not the quality I wanted but is doing what I want for now. May replace it at some time.
Garden furniture is now the same, general shortage of supply, waiting for deliveries, no deals around. As most of this stuff is made outside the EU, I cannot see it is brexit, more likely coronavirus. But please this is about materials supply, not a general rant about Brexit. I am off topic because OP was talking about wood.
