Personally, I haven’t seen a shift in prices... but availability has been lean which may eventually shift prices up a bit due to supply-demand rules.
I can’t help with those items - no experience there.
I’m taking the approach that if I want it, I’m starting my paperwork now. Despite the optimism you’ll read on various forums, I’m not as optimistic. I have a couple Form 1s in progress to get ahead of any potential and unfortunate walloping in Nov which may create an unbalanced gov situation.
...or maybe that’s just my excuse to buy a lot of stuff I “want”... you decide!!
