Does PSA do price adjustments/“Policy Adjustments” where if you buy a particular product at a certain price then a week or two later the price goes down for the same identical product?
No
Good to know 
I’ve always deleted those emails as soon as they hit my inbox…
Derp, I never paid attention to that 100 dollars drop. Good to know.
I didn’t know about the $100 part either. Would have been nice months ago lol now I know!
