You were referring to the announcements and these announcements are still available.
The actual pricing pages of course only show current prices. What would be the motivation for AWS to show outdated prices there as well? No other company I can think of does that and given the complexity of the pricing structure for AWS services that'd only confuse users even more.

Do you have an example for that or is this just hearsay?
> or as de facto decreases (widely but privately negotiated, e.g. "sticker price")
Privately negotiated deals aren't regular price reductions as they're only available for customers with a fairly large spend for such AWS services.
The only rule of thumb is what is posted on the pricing page is supposed to be what you get charged. No APIs exist for the most part, and the actual charges can sometimes differ anyway (e.g. grandfathered pricing etc.)
This is not a good look.
From your blog post:
> It's hard to come to a firm conclusion since pricing data is held very secretly (AWS quickly deletes announcements of historical price decreases).
There’s nothing wrong with “I missed that. Thanks, let me update the blog”.
I used "core" incorrectly
Widely, AWS doesn't negotiate on pricing. Small business get the list price or they can switch to another cloud. Medium and large businesses (from 100 employees to Fortune 500) get blanket discounts (excl. some specific line items) in exchange for a spend commitment, e.g. if you commit to at least $10M AWS spend per year, you'll get a 10% discount for all your spend. It doesn't give different discounts to S3 compared to other AWS products.
Do unique top-top-tier customers of AWS get special S3 pricing? Nice for them, but it isn't _widely_.
